You guys are really good at I.D. variants of 109s. When i look at it, i don't know what to look for, I just see a 109. it is better than most people who may just call it a A/C.
It's pretty tough with the later models. At first glance I look at the engine cowling, so it could have been a G-5/AS, G-6/AS, G-14/AS, G-10 or G-10/AS, or a K-4. It couldn't have been a G-5/AS because the G-5 never carried the Erla hood (the G-5 had a pressurized cockpit). It couldn't have been a K-4 because of the tail wheel.
Past that, it still could have been a G-6, -14, -10/AS or a G-10. I had to refer to my book on the 109 series (An Illustrated Study of the Messerschmitt Bf 109 F, G and K Series by Jochen Prien and Peter Rodeike- Great book). Luckily, this was a G-10, as evidenced by the Fo-987 oil cooler and the bulges in front of the exhaust stacks, indicating that it was equipped with a DB605D engine. It would have been much more difficult to distinguish had it been a G-10/AS, since it would have been largely similar to the G-6/AS or G-14/AS.
This seems to have been a G-10 converted from a G-6, as it looks like it has the teardrop shaped fairings for the landing gear on the wings, first used in the G-4, as opposed to those introduced on the G-14. It's hard to tell from those angles, though.
