I've come across a '37 Tula that has not been refurbished with correct pre-war stock (no reburb markings anywhere on metal or stock and it's pretty beat up) and has no import markings. Nice so far... Although there are no refurb markings or indications of refurbing the serial numbers don't match. AND most interestingly the MN is equiped with the Finn type swivels but there are no typical Finn markings no be found anywhere? Any ideas?...are there Finn NMs that don't have any Finn markings?? Or this this a total parts gun (seems not to be though). Sorry but I don't have any pics to put up yet. Your opinions or thoughts?
