In case you planned some interim patch, I've found mismatched pictures in the newest update, while working on pictures:
6 M3A1 - photo is not cast-hull M3A1 - correct was 3992 (as unit 244)
64,65 M15, M15A1 MGMC - photos have been mixed - according to Squadron/Signal "M3 Half-Track In Action", photo 2239 is surely M15A1, with its MGs slightly below cannon, while 2444 might be M15 (it is described so here:
https://commons.wikimedia.org/wiki/F...5-19430527.jpg and early date confirms it).
BTW, according to In Action, M15A1 had "revised and improved fire control system" and was produced from 10/43.
