A fabulous - and, since we didn't know existed - a groundbreaking find!This is a one inch square drive Bethlehem set.
I'm curious if the box has a free-swinging handle like the box for the 11/16-inch drive Set F. Photos of mine posted here.Original box.
* Set "A": 3/8-inch hex drive, in a little metal case
^ Set "B": 1/2-inch hex drive, in a "leather-like" case (six sockets are sizes from Set "D")
* Set "C": 7/16-inch hex drive, in a metal case (no ratchet)
* Set "C SPECIAL": 7/16-inch hex drive, in a metal case (with ratchet and ext/drive plug)
* Set "D": 1/2-inch hex drive, in a large metal case
^ Set "E": 1/2-inch hex drive (fifteen sockets all same sizes as set "D", but comes in a "leather-like" case with fewer handles and extensions)
* Set "F": 11/16-inch hex drive
* Set "G": 1/2-inch hex drive, in same case as Set "D", same handles, but "Splitdorf-Bethlehem" merger (1927-1929) logo, four (4) 4-point sockets, and four (4) special sockets (Alemite, wingnut, and two drag link bits)
* measured

Totally missed that, OTG! Where are you getting the "H" from? Is it on what's left of the label? As far as I know, we have no info (drive size, contents, etc) on a Type H set.I posted an h set box back on post 278


Looks like the same box.A fabulous - and, since we didn't know existed - a groundbreaking find!
Please post more photos, including some closeups of the sockets, when you get it cleaned up. Also the handles. As far as we know, the only set with tools that are branded 'BETHLEHEM' is the "F" set.

I am surmising they dubbed it Set "H". Set "A" through "G" are taken...
This looks like my set. I do not have the 1 3/8 socket or the lid for the box.I did find ads in several trade mags for what I assume is the 1-inch square drive set that @elidas just found! The drive size is not identified, but the socket opening sizes (1-3/8" to 2") are considerably larger than that of the 11/16-inch hex drive set (3/4" to 1-1/2"). So I am inferring it's the 1-inch drive set. It's odd they don't identify it as square drive. After making hex drive sets and nothing but hex drive sets from 3/8 to 11/16, you'd've thunk they would've mentioned moving to square drive. Splitdorf era, like Set "G". Looks like they dubbed it Set "XF", which I am sure is X for an even Extra Heavy Duty version of set "F" (11/16-inch drive).
First I found this one, which gave me what set nomenclature to look for.
With the set nomenclature, searching was much more effective. Here is one with a nice illustration. Which reveals that the original box is just like the box for the "F" set.
I will update the running list. And we really need to get 4.c to update post 1.
I don't have the lid either. I'm constantly looking! Ultra cool set, E!This looks like my set. I do not have the 1 3/8 socket or the lid for the box.
If you're still in touch with him, please see if he'll send some photos of the set and the label. I am not finding any trade mag ads for a Set "H". What drive size did he say it was?The guy I got it from had a pristine h set, this box was was his extra he upgraded from. It was a bethlehem splitdorf set from 28 he said.
Well I’m just jealous. That’s fantasticPossible unicorn. This is a one inch square drive Bethlehem set. Original box. I originally thought it was a BAT set because of the shape of the sockets. I got this and a original Walden set in the leather case and the wire ratchet for $25
So is it missing the ratchet handle or was it designed to just shove a cheater bar in and let it ripWell I’m just jealous. That’s fantastic
Will the sliding tee handle fit? Or is it too skinny? Note that there is NO bar shown in the illustration.So is it missing the ratchet handle or was it designed to just shove a cheater bar in and let it rip
The sliding "t" handle fits giving it almost 25 inches.Will the sliding tee handle fit? Or is it too skinny? Note that there is NO bar shown in the illustration.

Cool. Thanks.That's probably it
It will be while until get them cleaned up. I'm a little spooked by the copper plating.A fabulous - and, since we didn't know existed - a groundbreaking find!

2-1/4years later…I remember you experimenting with the idea of a printed version, LS, on a yellowish paper, something close to the finish on your lid, but I don't recall if you ever went through with it. I recommend using this mint-y label and finding someone with something like this...

I found out one of the guys I work with had temporary possession of a laser engraver!
He did some test runs with my pdf
and then inside one of my repro lids!
It took about an hour. I had left an area unfinished to ensure glue adhesion of my planned paper label, but didn’t do that. I have two more lids in the queue, one of which had the entire inside stained/finished. I’ll see how that one looks tomorrow, then decide if/how I want to finish this one.
Interesting, how the deep, open grain of the chestnut creates a mottled imprint, versus the same tool on smooth plywood.
That's the first "A" set I have seen with that label.This one is marked splitdorf electrical
Some kind of joint business entity, yes, but only for a few years (mid 20s), IIRC, the other sets we have seen were larger (D and G, as I recall), and they have a "SPLITDORF-BETHLEHEM ELECTRICAL COMPANY" decal.^ Wasn't "Bethlehem" acquired/absorbed by Splitdorf?

To put a finer point on this, because I had called it a "merger" here many times in the past, and that is what many trade mags called it (example notice in 1925 Motor Age linked here), in actuality, it more of an acquisition, by Bethlehem Spark Plug Co. (with Charles M. Schwab, the CEO of Bethlehem Steel, behind it) of 80% of Splitdorf stock. See hasty excerpts attached below.Some kind of joint business entity,
