Since this isn't quite a zombie thread yet.....
It's interesting to me that the SCSW mentions that two of the three product numbers (170098 for the black finish and 170041 for the stainless finish) for the 45 Recon were produced for RSR (a large Stocking Dealer), but RSR isn't mentioned with the third product number (170028).
That third number is the one specified to have come with the matching knife numbered to the gun.
The SCSW also mentions the nice aluminum double-lock Performance Center case, and some of the guns were shipped that way; others were in PC-marked plastic cases.
I've looked at photos of a couple of dozen 45 Recons, and it appears their serial numbers fall into two groups: the all-black ones start at REC0000 and go at least as far as 0309, and the all-stainless start as low as 0416 and go as high as 0596. This leads me to think that perhaps half of the run of 603 was black, and half stainless -- but that's a guess.
What's interesting about the ones that come with the knives (which are black) is that they were available with both the black- and the stainless-finish guns. Pictured below are the black 0283 with its knife, and the stainless 0460 with its knife. So it appears the PC marked a certain number of knives for both models, and those sets became product number 170028, and the remaining pistols were sold without the knives.
Long story short, it'll probably be difficult, short of a Jinks letter (and maybe not even then), to determine the number of units of 170028 -- 45 Recon models that came with the knives.
