The 35 caliber Smith & Wesson is a rare gun. S&W made less than 10,000 of them before switching to the 32 caliber automatic. They made less than 1,000 of those. But it has never commanded the price that an equally rare Colt automatic would. It's hard to say why. It may be because it was really a poor design, with an underweight bolt, awkwardly placed safeties, and no actual advantages, whereas even the earliest Colt 38 ACP automatics, despite their lack of safeties and odd take-down system, were Browning designs. They functioned well, their ammuntion was more powerful than 38 Special. In light of the Colt Model 1911 that they led to, they can clearly be seen as steps on the road to something better. The 38 ACP Pocket Hammer model was a useful weapon. The S&W 35, despite interesting (if not functional) features, led only to the 32 S&W automatic, and that was a dead end.
I think S&W collecting is just not as intense or prestigious as as Colt collecting. Maybe that is changing, because of Colt's long absence from the handgun scene, depsite its recent small-scale return, but that's the way it has been during my collecting life.
A few more points: First, using 32 ACP in a 35 S&W is not a good idea. It is more powerful than 35 S&W, and the 35 caliber pistol's bolt was already underweight for the 35 cartridge, which meant it was opening too fast and with too much force. That already made for some poor functioning. 32 ACP just increases that, and is semi-rimmed instead of rimless (which 35 S&W is) to boot.
Second, It seems to me that there is no need to call it the Model 1913. S&W never called it that, and with S&W's plethora of modern 4-digit model numbers, it's a bit confusing. S&W only made one type of 35 caliber automatic pistol, and nobody else did, anywhere, ever. But I suppose many, many people have never heard of it, so this point is debatable.
Finally, the best reference I know of about the 35 S&W is an article by Donald Simmons in the 1976 Gun DIgest Annual, titled: "Smith & Wesson 35 Auto Pistols – A History for Collectors". It is very thorough. You can find old Gun DIgests on Ebay, and Gun Digest sells a PDF download of this whole edition in their online store for $10. There really ought to be something more recent than 1976, but I don't know what it is.
