Before it's graphical update the Typhoon was a frankenstein monster. It had the power curve of one version, the prop blade count denoting another version, and the physical traits denoting yet a third version.
I don't believe that when the graphics were updated the flight model was changed at all.
You will need to compare the power curves to truly tell which version we have, despite any graphics (such as car door vs bubble hood). That is really what is important with our typhie.
The I-16 first received its M62 engine in early 1939. Given time for prototypes and then production, I think it is safe to say that 1939 is a good date for the I-16 in AH. This also plays into the fact that it was around in the many thousands by the time that Germany invaded in 1941. It would take time to produce and distribute so many thousands of planes by the time this invasion came around.
You list the FW190A5 as 6/43, and maybe that's specific to this model... But it's also 99% identical to the 190A4, and several other 190 models. The A-4 was introduced in July of '42, and however long it took to see combat, I doubt that was a full year. The only differences being about a 6-inch extension on the engine mounts, a first-aid kit in the squared radio hatch, and a different armored head-rest.
The 190A-5 is also very similar to many early jabo planes, such as the F-1. Often times all it took was a single centerline bomb to denote the plane was attack (keep in mind, 109E, 109F, etc, a single centerline bomb was all it took), and often these had different designations such as F-1, F-3, etc. These dates must also be taken into consideration when thinking about the timeline for our 190A-5's inclusion into a setup.
I have to wholeheartedly agree with Baumer on this one. It's nice to use as a reference, but foolish to use as the ONLY reference, for setting up some planeset, event, situation, etc. The entire thing is far too dynamic and un-even (gaps in planeset, etc) to leave it up to "just" the dates...
