Plomb Tool Company J100 types (Version 1.1 Updated 5/15/2023)

The J100 Keychain Screwdriver Project The information that will be posted to this thread has been many years in the making. Many of you have waited very patiently for the results of this research to be released. I have chosen to publish the research here, on the Garage Journal forum, because...

Here's another Plomb executive appearing on a J100 keychain screwdriver: Dillion Stevens, VP and Chairman of board. The first clipping is from the 2/11/1944 edition of Anvil Chorus, and the second clipping is from the 1/14/1944 issue. The third clipping (with the photo of Stevens) is from the...

I have reached out to my contact in Malco’s administration to see if these claims are valid or not. Keep in mind that anyone can join and post content here, so when a new member joins and drops a bombshell like this, I always suspect a troll.

I didn’t even post my Morris Pendleton J100s because I thought those were too obvious.😉

This one isn't a total surprise because I knew Galbreath was a high-ranking executive at Plomb, but it's nice to put a face with a name finally. The first clipping is from the 2/2/1945 issue of "Anvil Chorus." The anniversary pin awards listings is from the 7/6/1945 issue.

Four.cycle: I think I may have acquired a "sister" piece the unmarked version that you posted to this thread awhile back. Mine appears to have been made when there was a "Proto Mex" plant operating in Mexico. This later became the Urrea tool company that still exists today. Also, I guess I...

Lugz: Any idea if the "P.W. Senour" getting his 12-year service award in the 4/6/1945 issue might be the same guy whose name is on the back of this J100?

I am doing just that. Got them all downloaded and saved. What a great group of information with still more yet to come.

Thank you for contibuting those photos of your J100. That style of the front stamp on that piece dates its production to the mid-to later 1960s.

Terrific find, Lugz! “The Model 100 Goes To War”! I will check out the newsletters also. Thank you!

Thanks for contributing that photo. That one is from the 1950s based on the stamping.

Private Lugnutz: This is a great question, but a bit of a tougher one to answer. Prior to the use of die forging on J100s (which started in the late 1930s), the pieces were made using a power hammer (also called "trip hammer", of the type made popular by LIttle Giant and others), this...

I wanted to provide a bit of an update to the J100 Research Project as I know that a number of you are actively watching this thread and eargerly anticipating the release of my J100 research as soon as I put the finishing touches on it. It has been quite an effort over the past couple of...

Thank you for contributing that image. What a beauty!

I really appreciate your contribution, Alex. Thank you!

Thank you for sharing these images! I really appreciate it. You've got an early to mid 1970s piece there.

Hold that thought. Check this out. Looks like the same marking: https://www.bladesmithsforum.com/index.php?/topic/38561-anvil-identification/ If the guy on that thread is correct, it "appears to be a Soderfors, made in Sweden for Columbian between 1923 and 1927". Cast steel anvil (as...
