Udel: Thanks for posting. What I'm going to give you are a list of nitpicks b/c I'm a Sherman nut. Please feel free to ignore them -- you've done a great job. But here goes:
1) The applique patch on the left hull is too far fwd. Their placement was to guard the ammo bin stored behind the driver. Next Sherman, pay special attention to the plate placement (if they're required) toadmanstankpictures.com/firefly_10.jpg
2) tail lights. US made vehicles had only the upper left oval in red. Below it was a black slit. On the right tail light, were only two black slits -- no red there.
3) the long pry bar on the right hull roof edge -- both ends were brackets that were painted OD
4) the spare fire extinguishers on the rear corners of the engine deck -- were a British add-on. Wouldn't be found on French M4A4s.
5) applique armor plate above hull .30cal MG should not have a gap (which would have been a nasty shot trap). Next time, fill it in: toadmanstankpictures.com/firefly_22.jpg
6) your rear fenders are incorrect. There should not be toed-in but straight across -- regardless, with M4A4s with the dust guard mounting strips like your kit has, no rear fender was carried. They should just be removed.
Good luck. LIke I said, these are pretty specific DML M4A4 nitpicks -- feel free to ignore. Keep up the solid work. Post pictures of your projects in progress and people can give you pointers along the way, if you wish.
