TK 105-9 construction program
This letter (dated 1952-09-27) from Bofors to KAFT describes a proposed construction program for a 105 mm L/67 rifled tank gun, fed by two 7-round autoloader drums and placed in a heavily armored turret intended to be mounted in a 35-ton tank currently being under development at KAFT (project EMIL, of course). The letter mentions that 12 and 15 cm L/40 smoothbore guns are also possible alternatives but no further details are provided. There’s a list of blueprints for these guns but they are (as usual) missing from the archives because apparently the bureaucrats at the time hated historians.
