I don't believe it was intentional at all (to fool competition). The running theory initially on the alphabet Bearcats was that it was to fool competition but running 1,000 of each alphabet was was really for making manufacturing easier (probably to match the guards up with the frames after they both went their separate ways - gold anodation and black anodation), then a list of year by year manufacturing totals came out which pretty much settled the Alphabet Bearcat question...they just produced one heckuva lot of alphabet Bearcats from 1958 to 1962.
Who knows on the Ross flattops...there were 800 guns...800 exactly by the serial numbers...was that a day's worth of production for putting on those serial numbers?
I don't know that Ruger has another serial number record at the factory that is pre-manufacture date, you'd think they would in order to keep the feds happy through the mfg. process...or at least keep some kind of running tally somewhere close to the serial numbering machine. The manufacture date is when the gun has reached final inspect and has been testfired...that's the first date that goes in the day book. The only other date in the day book is the ship date.
In 1961 there were roughly 1,000 "D" Single-Sixes in a batch, in 1962 there were 600 T678 autos duplicated, 1966 roughly 1,000 duplicated RST4's just to name a few...and the real biggie was over 5,100 Single-Sixes in 1968 although this can be attributed to the thought that somebody forgot the 500000 range had already been used for the Super Single-Six a few years earlier.
I think the Ross guns exist they way they do because of simple human error like the first three examples above.
Who knows if they are a days production, but they could be.
Say the employee gets to running late on the day and just gets the guns numbered (the first run of 4684 to 5483) and figures he'll get them noted (in whatever record) the next day. Doesn't happen, he doesn't show up for work or who knows. So the next time a batch of guns gets serial numbered they start again at 4684 and do 800 guns. At some point somebody realized the mistake....was it when they were seeing duplicated numbers finally in the day book???
So by that time you would already have the 2nd batch of guns 4684 to 5483 that may have even been blued and going through their testfire...then when they go to the day book....OOps! The answer...somebody forgot something, eh???
Who knows when it was discovered...but I do not believe it was to fool the competition.
Thinking about this I am also reminded about the 500 .41 Blackhawks that were duplicated in 1967 as well as the two batches of Single-Sixes in 1967 (a batch of 100 and another 1,100+) that actually got out of the factory without having a "D" stamped at the serial number. The factory covered their butts by putting the "D" in the books though. :roll:
Yes, you can be sure that as long as humans are involved, something is bound to be messed up.
