Three-pin scales vs. single pin

When did Camillus switch from traditional three-pin scales to single-pin with two molded protrusions inserted through holes in the liner? Did the change happen all at once? Can the type of pinning be used to date a knife? Thanks!

 

Perhaps something like the #67 stockman as an example. I believe it was made (sequentially) with both type scales and also (again sequentially) with both 1095 and one of the stainless grades.

 

Thank you Phil. Can I assume it then took a few years until most of the Camillus had also been switched to the Delrin stud construction?

 

I just searched though the 1976 and 1977 catalogs, as reproduced here. Looking at the basic "Cabone" scale knives (such as the #67, for example) they were three-pin in 1976 and one-pin ("Delrin stud") in 1977. I imagine that some of the actual production during each of those years did not reflect this but it seems can we assume that 1976-1977 is the date for the switchover to have occurred. It's interesting to note that this change would not have coincided with the change from 440A to 420HC that we suspect happened around 1990. I'm surely no expert so any clarification (or confirmation) would be welcome! Thanks everyone.

 

From this image it appears that this liner could be used with either single-pin (Delrin stud) or three-pin (traditional) construction. Is that correct?

 

Did these Camillus-made Uncle Henry models use Swinden Key construction or conventional pivot pin construction? And can they be identified as Camillus-made by the "SCC" tang stamp?

 

Thanks Bert. What you say makes sense-all that would have been required was to drill (or punch) a couple of extra holes.

 

Thanks Phil for adding to our understanding of the transition.

 

Thanks black mamba. That was also my assumption, but I was wondering only because these are particular Uncle Henry models. I haven't looked carefully enough to notice blade differences. Otherwise, if someone liked the Uncle Henrys, but not Swindon construction, these S.C.C. stamped knives might be the ones to seek!

 

black mamba I just realized I have a Schrade-built 897UH in my pocket and compared it with the image above. I can't discern any differences except the California clip main blade might be a bit wider in the Camillus version, but that could also be a function of the optics. What blade differences are you aware of? Thanks.

 

Thanks Phil! That pretty much clarifies it all. Now to search for those SCC-marked Uncle Henry Stockmans (Stockmen?)
