Why are they called J & K valves...?

[DandyDon]

I know the story my Tech Inst told me, which he got from his FBI Inst - but I'm gonna ask: What's your story...?

Valve with reserve was item "J", valve without reserve item "K".

That's actually covered in a current thread.

A quick search indicates that they were Items J and K in a catalog. I've heard a lot of stories, but there is also a shot of the catalog page which shows the valves identified by items J and K.

So, what's your story Don?

Walter's right - as usual, and I missed it over there in the Octo thread. It was mentioned there.

Sears & Roebuck catalogs had simple numbering systems that started over many times through the 400 page books 20 yrs ago. In Scuba equipment, you had to to specify which catalog and which page you were ordering from then select #J or #K valve for the tank you ordered.

Those were the only valves offered, but mixed with other items on the same page with other codes.

It was a US Divers catalog, I believe.

Really?! Sears is the stated source on the other thread. Now we have a new questions.

Sears was said, but it was also corrected. It was the 1953 US Divers catalog. The link SDdiver1 provided is excellent.

It actually came from the J & K bins at U.S. Divers.

I printed out the catalog and sent it to my Tech Inst - he'll enjoy it, and we'll both be corrected.
