Picked up 2 15/16 x 1 inch which have slight differences. Made in Canada Marked 185. These are fairly common in Alberta and no others that look like them. They were also made chromed but I have only seen pictures. Does anyone know any more about them?
I have an idea that  the chrome ones that are shown in the ETF catalog may be the same ones. Has anyone seen a similar wrench marked ETF? I have not.
The other possibility is that I need to cut back on my meds

don't cut back on your meds. You will turn into a tool addict . looking at catalogs. stopping at tool stores ,flea markets and yard sales.
You will be on the computer researching tools more than paying attention to family life.Your desk will be cluttered with slips of paper with unknown numbers on.At family affairs you will not know what anyone is talking about thinking about the tools that nobody is interested in. Just ask my wife.   LOL   bob w.

Can you post photos?

I've made a few half-hearted attempts to run down some info on these, but have found nothing to date.

(I'll point out that the correct spelling is "DublHex", though...)

Sorry! Forgot to add pics.
