Phil Steele very kindly presented me with an SU-76 from Wizard models, remarking that he thought it was about the right scale, if somewhat small. He added that he thought my existing model from QRF was “probably a bit big”.
What ensued was one of those wine-and-cheese discussions in which I came round to the idea that the QRF probably was a bit big, but I felt that the Wizard was “probably a bit small”. The next morning I cheated and got the tape measure out.
Cutting a long story short it turned out that the QRF was spot on for a 1:100 model at 49mm by 27mm and that the Wizard worked out at 1:125, not the 1:144 that I suspected it to be. So we were both wrong, and my new Suka will join the Japanese Vickers light tanks, which I use at T-60 susbstitutes, and which look right next to it.
In the photo you can see a T-60, also kindly presented by Phil, which I have not measured but might also be “a bit small”. He has run a similar exercise on the BA-64 on his “P.B. Eye-candy” blog The new Soldiers in Plastic Soviets in summer uniform are in the background.
