Hi folks, I can't seem to get onto alloy artifacts right now. Can anyone she'd any light on Wm cissell mfg Co out of Louisville ky?
Also a no 604 so wrench Hudson and Thurber Co ?
Well, I'm in the middle of a blizzard.... I'm not kidding ... it's crazy up here on the mountain!!! We are supposed to get well over 2 feet.... electric Co expects 90 percent of my county to be without power for some length of time... for now, I still have it!

Hudson & Thurber was an agricultural equipment mfg Co. Would have to assume that wrench came with a particular piece of equipment.
Here's the history on Hudsonhttp://www.hdhudson.com/website/documents/about-us/hd-hudson-history.pdf

Wm. M. cissell mfg Co manufactured laundry equipment, Irons, steam boards, driers, and the like.

Hope this helps

Bird, check your link to Alloy Artifacts.  It should be either alloy-artifacts.org or alloy-artifacts.com.  Both work.
