Citroën-Kegresse B2 K1

Citroën-Kegresse C4 P.17 (ID is correct, it's just listed different compared to the rest of the same model)
https://www.imcdb.org/vehicle_1812372-Citro%C3%ABn-K%C3%A9gresse-P17.html

I think that this should probably be listed as CWS wz. 28, rather than under Citroën-Kégresse. CWS is already in the additional info, that is the Polish factory that built these, based on the chassis they bought from Citreon.

Pz.Kpfw.38(t) Ausf.D (To be consistent with the way other panzers are named). Built for Germany, not built in Germany.

Crossley 29M (no "A", no space between 29 and M). Made for Hungary.
https://www.imcdb.org/vehicle_1165273-Crossley-A-29-M-1930.html

I discovered that the Vickers-Crossley Armoured Car has some entries under Vickers and some under Crossley. I don't know if you want to create a new make specifically for these, since they were built cooperatively with Vickers doing the armor and Crossley doing the chassis (hence Vickers-Crossley), or just put them under Vickers and set Crossley as the model name. I don't really care either way. I don't know if "Model 25" is actually a real, valid name. I've always seen them called just "Vickers-Crossley Armoured Car". "IGA1" can be set as the model code.
These two are regular British examples:

https://www.imcdb.org/vehicle_171607-Vickers-Crossley-Model-25.html - clear additional info, that is wrong
These two are Japanese examples. Please add "Type 87 Armored Car" as the additional info and set origin England, made for Japan.
