Unusual Yugoslavian Model 24/47?

I purchased a Model 24/47 today, and it is different from the other 24/47s I own.I wanted to get the forum's input on it. It has a mint bore and the wooden stock and handguard are both mint. The bluing on the gun is also excellent. The bolt number does not match the receiver number. The receiver number appears weird to me. The four digit serial number has a symbol or perhaps a letter in front of it that looks like a Japanese pagota. It may be a weird A. The four digit serial number matching the receiver is stamped into the stock near the butt like other 24/47s, but there is only the four digit number, no letters or the weird looking symbol on the receiver. The bolt has a capital S stamped on the stem and the numbers 9379 are stamped on the bolt as other 24/47s. The floorplate is mismatched with the number 8515 stamped on it. Above the number, several inches up is the weird looking pagota symbol. The rifle has M 24/47 on the left receiver ring also with the importer's billboard. Further down on the left receiver wall is stamped 3AB,a symbol that looks like a capital Q, and the pagota symbol again with 44. Is this a typical 24/47 with a mismatched rifle with normal Yugo alphabetical writing or is it different?

Photos would be better than descriptions but it sounds like normal Yugo lettering to me. Lot of odd looking symbols to us English speakers.

I believe some of the early Yugos were built on left over parts from WWII and they stamped their own acceptance marks on them when they built the rifles.

ive read on other forums they only did strings of 4 digit numbers. once they hit 9999 theyd start a new serial string.. A9999 followed by Bxxxx
