RE: manufacturing item #70-145304-A2 from two parts
Due to a lack of 35 mm thick plate 1232 mm in width, we are forced to produce item #70-145304-A2 from two parts with a perpendicular joint.
We have the agreement of military representative at factory #180, Engineer-Colonel M.S. Bazumov, to produce 40 units.
We ask for your permission to continue producing this item from two parts.

Permission to build more than 40 hulls was not obtained. At most 39 hulls were converted into tanks by the start of T-70B production at the factory, and the remaining hull eventually ended up in a museum.
