Hmmm, my 1929(?) M17 action has no "BO" or even a serial number on the bottom of the action. The good folks at Remington seem to have been very inconsistent over the years.
Speaking of inconsistency, I also, popped the stock off of the M10 tonight and dropped the still assembled action into some nice garage-chilled diesel fuel for an extended soak to, hopefully, soften (& dissolve?) years of accumulated dirt and hardened lubricants (oh, if only I had a nice, warm, ultrasonic cleaner...). I then dragged the front half of this old turkey shooter over to my big lighted magnifier for a closer look at the hidden serial numbers reportedly out of sight on the bottom of the barrel. By moving the slide arm out of the way they can barely be seen, and.....this barrel is numbered to the action with the very same SN. If this is, indeed, a circa 1925 gun then why no date codes on the barrel? I'm perplexed.
