R.R....excellent...let me see if I have this correct...132102 is a standard lock, while 132790 has the improved lock..that's only 688 numbers apart...Reb87 has one in the 132,000 range, maybe he will be able to close the gap if his is between 132102 & 132790..But thanks to RR, we can assume for the moment that the improved lock was incorporated somwhere in the 132,000 range...It will be interesting to see if the 1900 switched over in the same year as the '94

t1958...Remington was still patenting SxS items in the 1970's...and...Remington never came close to achieving the Flues lock time of 1/625 of a second, in fact the Flues line wasn't operational at that moment...Remington was still facing stiff competition from the Ithaca's transitional models, the Lewis and the Manier. Since the very first days of wing shooting, lock time was on the tongues of shooters, starting with matchlocks. Matchlocks and flintlocks have more hang time than lock time and it became very ingrained in the minds of the shooting sportsman. It may not have completely left yet.

Thanks to all for contributing to the further understanding of this venerable shotgun.
