Nicely done 109 klem. You didn't do a bad job on that weathering. I like that you got some oil staining on the botom as the 109's were oil leakers. paint chipping looks excellent even over the decals. That brown look great not too yellow. One thing I noticed is that type of prop was not metal and would not show metal chipping.
now I have a question. On the box what type of 109 does it claim to be? this is no fault on your part as you built it strait out of the box, but that 109 is suffering from an identity crisis. It has features of both a bf109F-4Z/trop ,an early bf109G-2/trop. and even a G-6 (DF loop moran antenna mount?). the marking seem to suggest it's a F-4. I am asking because I was planning on building a F-4 special which is close to a F-4Z, which your bird seems to be a better starting point for and would require far less work then to modify a hasegawa 109G. For that price you can't knock it, it really builds into a nice model despite some accuracy problems.
BTW your pics are excellent very clear and that was why I was able to see all the detail.
