Does anyone have any scale plan drawing for this vehicle? I'm thinking of scratching one using the Takom Type 69 as a base. I've got plenty of reference but could do with some plans.

Are you sure that it is based on the t-69 chassis? I see a line between the wheels that seems to suggest a T-59 chassis. T-69 should have flat sides, if I am not wrong.

I think there may have been a mix of Type 59 and 69 - probably converted as chassis became available:

So far as I can tell the Type 69 has a squarer lower front glacis plate. Because of this the gap in front of the first roadwheel is filled, but all the others are the same as on a T-55.
