So, I decided to pull the stock on this Super 10 to check its serial number. That wasn't necessary; I discovered the s/n is stamped in the trigger guard tang inlet. Stock number matches the frame serial number, and is stamped "43417x RF".
Serial number on the forend wood is shown, also with the "RF" suffix. More pics are included here, of the forend iron and the beavertail.
I forgot to add in my earlier posts that this NID Super 10 has twin ivories; mid bead is exactly at 16" on its 32" barerls. Also that the gun came out of the Finger Lakes country of western NY. Possibly the gun was assembled later than the frame s/n would indicate, or it may have been owned by a factory employee who had it done up with the later style wood and pad in the 30's? Frank
