Identify my Drulov Single-shot 22LR.

[85919080IPSC]

Can anyone point me to information on this Drulov. My bolt is round and has serrations al the way around the outside. I've seen one with a different bolt on the back, more oval shaped, and very smooth finish, which is identified as a Model 70 or 75. Appreciate any pointers. I don't seem to be able to attached a picture, just use a URL to point to a picture.

Thank you.

Sounds like you are referring to a handgun. Is it similar to the one in this photo?
