Howdy and welcome to parallax Bill's Yugo Mauser forum! We can help you out with most of the markings. Unfortunately, most of those single letter stamps can only be defined as "Inspection stamps" since the records for them were lost or destroyed long ago.

If I may offer a suggestion? read through the 'sticky posts' at the top of the topic listings. There's a lot of info on the markings, history and what not of these fine weapons. But to address this one specifically...

The crest on the receiver ring. that is the Communist government of Yugoslavia crest. The 5 torches symbolize the 5 republics that made up Yugoslavia. Of course, Tito was the ruler of all. that 1943 date on the crest represents when Tito established his governing of the country.

M24/47 is of course, the model number. it represents two rifles in one. The first was a model 1924 either purchased from FN in belgium or manufactured byu the Yugos under license from them in the 1930s for the most part. After WWII, the rifles were refurbished, evaluated, repaired as necessary, original prewar markings scrubbed and new post war markings applied creating a new model, the M24/47. The '47' represents 1947, the year the refurbishment program began.

The Cyrillic lettering on the Side rail represents in Latin script, PREDUZECE 44. That is the factory code adopted in Sept of 1947 for the main Yugo arms factory at Kragujevac. That's the same thing on the ricasso of your bayonet. You're fortunate that the bayo/scabbard match. that is the exception rather than the rule.

the circled BK on the stock and elsewhere, possibly appearing in a lopsided square too, is the Cyrillic for VK, a military control stamp.

Looks like the original walnut stock as opposed to a later era elm replacement. You'll want to clean it thoroughly. Cosmoline will ooze out all over everything the first time it warms up. Same thing for the bolt if you've not taken it down. They likely packed it full of cosmo too.

That's the quick over view anyway. as I said, you'll find more detail in the stickies if you're interested. I hope you will be!
For the record, there's a whole book on Yugo Mausers. Inexpensive too. that's covered in the stickies too.

Once again, welcome to our forum and the world of Yugo mauser collecting!
