Two years ago I bought a 1907 Savage pistol from a MD dealer. I guess they weren't familiar with the pistol as they submitted the paperwork as No Serial Number (I didn't notice this error until later when I was filing away the paperwork). It does have a serial number in a somewhat strange place (edge of frame under barrel). I just got a call from MD State Police inquiring about this pistol and asking to confirm if in fact it doesn't have a serial number. Interesting how this would come up 2 years later.
