How are the last 3 sentences ridiculous?
The Bf. 109G-6/R1 is the designation for a Bf. 109G-6 with the R1 bomb rack and arming mechanism Ruestsatz.
/R3 is for a drop tank rack.
/R2 is for the Wgr 21 tubes.
/R6 is for underwing 20mm gondolas.
We have all of these as options in the hangar in game. Obviously by HTC standards these are NOT different models.
In fact, since we have the WGr 21 tubes in game for several models and they are a much larger modification than the R4M's racks, the assertion that the Me 262A-1a/R1 would have to be a different model is a bit ridiculous.
Whoops sorry, the WGr 21 tubes are Ruestsatz 2, R4 is MK 108 underwing gondolas.
Just added up the in hangar options for the Fw 190 and Bf 109. If every Ruestsatz kit were a different aircraft we would have 16 different models of the Fw 190 and 59 models of the Bf 109, a total of 75 models between the two aircraft.
This is only if you have one kit per aircraft, though, no mixing, which definitely happened. So, accurately, we would have even more.
Note, though, I didn't add up any of the wing armament variations in the 190's (I don't remember if these carried separate designations), but I did add in the 30mm option for the Bf 109G-14, which in real life would have been the Bf 109G-14/U4 (standing for a factory modification).
