I built one not too long ago; an old M5A1 that I was intending to build into a Yugoslav Partisan Stuart with a Flak 38 gun, but then I realized I should’ve gotten an M3A3 instead.
I built it and it was a so-so build for me; then I built the M8 Scott HMC, using the lessons I learned from the M5A1; that one came out much better, despite the shortcomings of the early Tamiya kit.
