DonZ, Though I can't match the characters up exactly Georgian script looks very much to be a possibility.

Kuduae, Thank you for your reply. The bolt on my 1910 rifle does look like your 1900 bolt. The bolt on my 1910 does have the crown over B and crown over U proof markings and the underside of the bolt root is serialized matching the receiver and barrel.

Thank you both for your input.
