I have not looked at the periodic table lately that must be a new one...
Snerk.Lectromium?...[ ]...I have not looked at the periodic table lately that must be a new one...

So from what I read and see in this thread, SK raised panel wrenches adopted the Lectrolite style from here (1953) to eternity. Is that correct?--> Starting with the LC/SK collaboration circa 1953, all LC raised panel wrenches are dual-marked S-K Lectrolite. This became LC's own main line end wrench. If you have an end wrench that looks just like a classic SK raised panel but is marked with Lectrolite only, it was made during that brief Post-R period just before the LC/SK era.
--> By about 1964, Wayne killed off the Lectrolite and Tru-Fit brand names. It also did away with the Tru-Fit recessed panel design altogether. At this time, the SEARS brand wrenches begin appearing with the famous BF JAPAN mark, which were essentially exact counterfeits of the Tru-Fit design that Wayne abandoned. I suspect Wayne gave Sears its blessing to have its old Tru-Fit wrenches made by anyone Sears wanted.


Yes, this is essentially correct. All of the raised panel SK/Lectrolite end wrenches starting in 1953 were made in LC's Defiance Ohio plant. When Wayne bought out Lectrolite and SK in 1962, it dropped the Lectrolite name so that the raised panel SK wrenches now only showed SK (or later SK Tools under Dresser), but were still being produced in the LC Defiance Ohio factory until it was closed (IIRC, by Ideal), which ended the raised panel design.So from what I read and see in this thread, SK raised panel wrenches adopted the Lectrolite style from here (1953) to eternity. Is that correct?
What did SK combination wrenches look like before they adopted the Lectrolite raised panel style?
Your math is fine, Don, but Lectrolite was not formed until 1932. How can that be so? Interestingly, that catalog seems to be referring to Milwaukee Tool & Forge, one of their main predecessors, which did form in 1917, and first used "True-Fit" as a brand name, much later inherited and stylistically transformed into "Tru-Fit" by Lectrolite.According to their 1949 plier catalog, they started in 1917 if my math is correct.
Looks just like the ones I got recently. Moved onto the old husky stuff now though
I found another “truth in advertising” combo at a Saturday estate sale. Tru-fit on one side and Lectrolite on the other.Snerk.
The first thing that comes to my mind is a portmanteau-ish compositional branding attempt, such as Fairalloy (Fairmount alloy), but given Lectrolite's quirky compositional-related markings (e.g., turning "FORGED ALLOY STEEL" on wrench shanks into the unmistakably conspicuous "FORGED (BLANK) STEEL" - see post #5) and the much more common and even more irrational ".05 CHROMIUM .05 VANADIUM" markings, I suspect it could also be related to their legal issues with the FTC in 1939.
EDIT:
Well, I scrolled back through this thread to link a post on that subject that isn't there. I searched the DBE thread and the Tappet Wrenches thread to see if I had left it there instead, but I can't find it anywhere.
This is something I found last year and apparently forgot to post.
We have wondered often in the past about those weird .05 markings. GJ is littered with me pointing out again and again in numerous threads that .05% is not even close to the amount of chromium and vanadium in AISI 6000 series formula CV wrenches of that era. It is so far off that I openly wondered if maybe they had the decimal point in the wrong place and didn't bother to fix it, but remarked that even .5 Cr and .5 V would be too low for AISI 6000 CV. I also remarked that it is too low for "New Emergency" AISI 8000 series triple-alloy formulas.
With the strong caveat that I am only speculating, deriving a possible conclusion based on available information, one possible explanation is that the the precise .05 Cr and .05 V markings could be Lectrolite's response to the 1939 FTC smackdown for false advertising and marketing. Who knows what the steel actually is (high Carbon, probably, maybe something else) with ridiculously low trace amounts of Chromium and Vanadium.
Conversely, maybe those markings are what the FTC was reacting to, thinking that most consumers, uneducated on the precise math involved, are going to see the Chromium and Vanadium markings and mistake the wrenches as CV.
Either way, in that same vein, maybe "Lectromium" was an attempt to word brand the .05 Cr .05 V formula.


i have one somewhere. didnt know they were rare. i come across them quite a bitNice DBE, Don. Now you need to get 3002, 3003, 3005, 3006 and a rare 3007 (1 1/16-1 1/8) - the last one I saw only once for sale on E-bay, but it was a wrong period to add to my set...
Which state are you from?i have one somewhere. didnt know they were rare. i come across them quite a bit
vermont. if you need one i can ship. id have to look around i currently have most of my wrenches in some boxes until i have the energy the sort through them but you can have for just the shipping costWhich state are you from?
