Where to obtain Serial number ranges for Stevens 520-30 and 620?

Hey all,
I have been trying to locate the serial number ranges for the 520-30 and the 620 to see where they fall in the category of riot or trench. Any help would be appreciated. Thank you.

The 520 and 620 Military riot guns fall into the lower serial number range for these guns while the trench guns seem to be in the upper range. Off the top of my head I can't remember just where the break in the serial number occurs, but I'll check some of my data when I get home late tonight and let you know.

Tom,
Thank you. My 520 number is 5234* and the 620 is 1884*. I have two barrels that are 4694* and 3944* range. Thank you for the help.

For 520s, there are mostly trench guns from about s/n 50,000 on up. For 620s, there seems to be mostly trench guns about 2/n 20,000.

Are you trying to tell if you barrels are riot or trench gun barrels? They are marked differently.

Tom,
Thanks for the info. Well I'm sure the barrels are not trench as they do not have the three grooves for the heat shield. The barrels are both factory 20" cyl choke. However number 46943 is proofed and barrel 39448 is not proofed. To bad I didn't have a trench barrel for that 520 since it seems to fall under the trench gun range. Oh well...it's a riot gun now.
