I don't claim to be mauser smart and this one certainly doesn't conform to any of the norms. What I believe I have here is a byf 44 i block completed on a byf43 receiver. All of the features scream mid/late 44 (stamped parts, numbering conventions, etc), but what has me wondering is why this one is serial numbered on the receiver, rather than on the barrel like most 44 i blocks would be. Was it serial numbered in the i block of 43 and then integrated later? But why the letter suffix in line rather than below? Interested to hear more knowledgeable folks chime in. Good rifle overall that has it's original 1944sling.
