Spitfire MkI and Hurri MkI MkII Reflector Gunsight

[bustr]

If our Spitfire and Hurricane MkI's are pre 1941 birds then, shouldn't their MkII gunsights be the oval or round glass style? Here is a link to a MkII oval glass type for sale. It's halfway down the page.

Wish 1.) If this is true I wish that the correct gunsight type be reworked into the spit1 and Hurri1.

--------------------------------------------------------------------------------------

The first change in the design was made in 1941. when the circular reflector glass was replaced by one 114 mm (4.5 in) square, the circular design having been found to have slight optical aberrations. This modification was designated Mk IIs, later Mk II*, fixed gun reflector sight. Existing sights were retrofitted with new sights heads, and the circular sight heads are now highly prized by collectors. The dimming screen was discontinued, as it was said to be rarely used.

Wish 2.) Please correct the rectangular MkII reflector glass to a square 114mm plate with rounded corners.

--------------------------------------------------------------------------------------

Currently all of the british aricraft in AH using the MkII square plate sight with the MkII stamp designation when zoomed, are pre 1941 because of the MkII logo. Pre-1941 bases refitted starting in 1941 with the square reflector glass would have MkII* logo. Our current MkII's zoomed in logo reads MkII and should be MkII*. The serial number line reads:  AM Serial NO. 20618/48 <----Made in 1948. One would think 41, 42, 43, or 44.

On this page you can see a MkII* base made in 1943. Also a MkIIL with the rocket adjustment used in Typhoons.

Wish 3.) Please correct the manufacturers designation information on the zoomed MkII sights.

Another good example of a MkII round glass version 1940.

Wish 2.) Please correct the rectangular MkII reflector glass to a square 114mm plate with rounded corners.

the glass is square, but its set at 45deg to the sight line so it appears rectangular (well trapezoid )

I'll grant that and from the Old Scots Law am admonished.

I cropped it and looked at 1000% zoom to calc it. You are right. The top corners still need a quarter round on them. The serials\date and MkII* need updating. Unless you like knowing the MkII in the game was a copy of someones real MkII* refurbished in 1948 with the /48 year staring at you. I thought this game was limited to 1945. Is the MkII in our game copied from one sitting on a desk in HTC's offices?

The info I gave should make it simple for the necessary mods to place a round glass pre 1941 MkII in the spit1 and Hurri1 with a MkII and /38, /39 or /40 serial, while placing a post 1940 MkII* /41-44 with rounded edges square glass in the spit5-14, Tiffy, Tempest and change the serial\date and MkII* in the Tempest since the lense reflects onto the windscreen. The tiffy should actualy have the MkIIL with the reflector plate angle adjust knob on the right hand side.

Check the bottom of this page. A MkII pre/41 in a Mossi VI cockpit. In game it looks like we have the MkIIIA* or MkIIIN which were standard on Mossie and other multiengined aircraft. The MkIII was built under license in the U.S. as the N9 we see in our P51C in the game.

This page has a Hurri cockpit with and excellent picture of the rounded edged square glass on a post 1940 MkII*.

I thought it was circle to.

Early SpitI and HurriI




GM2 MkI --- Mounted in a Hurri angled to match reflector plate opticly with the wind screen to account for double image distortion. Similare problems were encountered with the spit. Version that should be in our Spit Mk1 and Hurric Mk1. Used in early Beaufighters.

               

The first change in the design was made in 1941 when the circular reflector glass was replaced by one 114 mm (4.5 in) square, the circular design having been found to have slight optical aberrations. This modification was designated Mk IIs, later Mk II*, fixed gun reflector sight. Existing sights were retrofitted with new sights heads, and the circular sight heads are now highly prized by collectors. The dimming screen was discontinued, as it was said to be rarely used.

When rockets came into widespread use, a special version of the GM2 was designed in co-operation with Farnborough, to allow for the increased gravity drop of these projectiles. The reflector screen was made to tilt forward by the pilot from 0 to 5 degrees depression, according to airspeed and the known drop of the missile being used. This modification, which involved the replacement of the sight head, became known as the type 1 Mk II conversion, and the sight then became the Mk IIL.



GM2 - MkIIS or MkII* --- What HTC currently uses in all spit, hurri and typhoon. Notice pronounced rounding of reflector plate corners.




GM2 - Mk2L --- Used in Hurri IIC\D and Typhoon. Dial changes the angle of the reflector glass by 5 degrees for bombs and rockets.



GM2 - MkIII - Used in Typhoon and Tempest to project reticle driectly onto the windscreen. Shroud cover is to keep the pilots eyes from being impacted by the projector lense.



GJ3 - MkIIIN - Used without the reflector plate in our Mossi6 projecting onto the windscreen.



American versions of the GM2 and GJ3

Mk8 Mod6 - Used by the NAVY, projects onto the windscreen or mounted glass plate.



Mk8 Mod8 - Used in fighters and carrier bombers.



N9\Mk9 - Used in gunner postions.

1)  You woke up from your nap remembering a thread from over two years ago?   

2)  I'm all for accuracy with the time period, but the Hurri/Spit-I aren't exactly OP with their upgrade...  cant HTCs invest their time more fruitfuly for you (and the rest of us)?

Blame spitter, he bumped it and I realised pictures on the page are better than words.

Gamers are not known for reading game manuals let alone books.

[spitter123]

all I said is that I thought that those sights were meant to be round is all. If you're considering this a bump then, Fine, It's a bump...

Shhhhhhsh, I always regretted I didn't do a better job of the presentation.

One day you too will be an older than dirt AH player and can tell a new player shhhhsh while fixing a long lost regret. Common don't you like the pretty pictures and some histroical knowlege?

It's good work though bustr
