Symbols:
1.) an X with a little star over it
2.) a little symbol that somewhat resembles the browning symbol, kind of looks like the & with legs.
3.) PV
4.) Arrow facing the rear of the action arrow tip is made up of 3 or 4 lines.
5.) 5 digit serial number starting with C and ending with 1.

Any Ideas? The bolt has the same serial number on its bottom side.

the X with a star over it could be an Israeli star of david. The & with legs sounds like a Czech rampant lion proof.

My guess is an Israeli issued VZ24. Is it stamped 7.62 on the receiver ring?

No other markings other than the serial number. This is a custom rifle now chambered in 280 AI. Any other place to look for hints?

Gunsmith, without researching, said he thinks it may be Austrian.

The "PV" and Browning-like symbol sounds like Belgium proof marks, so maybe an FN. You might try a Google search on proof marks which may bring up the proof mark section of the Blue Book.

any chance of a picture? It's worth 1000 words, don'tcha know?

Try this link as it has many proof marks: Proof Marks

Pictures, naw that would make too much since!

I am going to borrow a digital camera and then post. Thanks everyone for the thoughts and ideas.
