So we have here new evidence of produce of PPD BRAMIT
The issue of the developer of the jamming device for the SVT-40 remained unresolved. By design, the muffler for the SVT-40 bears no resemblance to the Bramit device, which means that the authorship of Ivan Grigoryevich Mitin is not obvious on this basis. However, as follows from the published biographical data of I.G. Mitin, in 1938-41 he developed PBS for the Tokarev submachine gun (PPT “Bramit”), Degtyarev submachine gun (PPD “Bramit”) and Tokarev SVT self-loading rifle. At that time, he was imprisoned for anti-Soviet activities and worked in the Ostekhburo of the NKVD of the USSR, leading a group working on silent weapons. Nothing is known about other silent weapons development centers in the USSR… This makes it likely that the described silencer is attributed to Mitin’s authorship. Whether this is actually the case remains to be seen. In any case, the topic of the history of the creation of domestic PBS cannot be considered closed.
