Twister'sPa:

It sounds like Italian choke marks:

* - Full Choke
** - Improved-modified or 3/4 Choke
*** - Modified
**** - Improved-cylinder or 1/4 Choke
CL - Cylinder.

This is from memory and I believe I recall correctly and I think that some of the Browning A-5's were marked that way.

Kind Regards,
