Slat Glovebox Lock
Later slatgrills had a glovebox. It had a lock that is quite hard to find.
I have an idea that it might be the same lock as the 1937 Chev pickup. Can anybody confirm this?
Perhaps if it is, a Chevrolet lock could be rekeyed for H700…
Here is the page from the Chevrolet parts book kindly sent to me by “Lou”, a Chevrolet pickup collector… trying to get more data, I think the 10.266 reference is a “group” number… whatever that is…
The lock on the left is whats left of an original slatgrill glove box lock. The two on the right are 1937 Chevrolet pickups…

From Robert de Ruyter:
According to TM 10-1186:
Glove compartment added at MB 120,697
Starting at MB 120,697 door A3434 was used (hole for lock is 1 & 1/2 inches from top), after MB 137,909 door changed to A3943 (hole for lock is 1 & 1/16 inches from top)
Starting at MB 120,697 lock parts A3531 case, A3532 cylinder, A3535 spring, A3536 lock bolt, A3537 3/4in nut was used.
Staring at MB 134,356 an A3823 lock assembly was used.
Starting at MB 137,909 the A3818 striker was added..
I found the interesting info in the 1939 Briggs & Stratton automotive lock catalog:
I suspect the early glove box lock was a Briggs & Stratton 45795
A catalog of Briggs & Stratton automotive locks used to be found at
1930’s Briggs & Stratton catalog

It looks like the tool box locks might have been 85345 and the tire lock housing was a 80330 if Briggs & Stratton was the supplier.

New data!
I was very lucky. I won the following lock on eBay two weeks ago (for $14!), and it was listed by the seller as:
“1930’s – 50’s Chevrolet GMC Pick Glove box Lock NOS”
Per the B&S catalog referenced above, this almost certainly has to be a Briggs & Stratton 45795
It appears to have been first used on a 1935 La Fayette and some Pontiac models. By 1936 the 45795 was used by Chevrolet in some commercial vehicles (pickup trucks), and in Nash cars. In 1937 it was used by Pierce-Arrow, and by Chevrolet in trucks. It looks to have been used by Chevrolet into the 1940’s on certain heavy commercial trucks that had a flat glove box.
I don’t see any example of it being used on the Hudson, so that does not support the idea that the H in H700 comes form Hudson, but then it could have been from some other Hudson model, such as a sedan used by the Army. It would have been easy for Briggs and Stratton to key everything the same, because they were supplying the locks for all these manufacturers.
The lock pictured below measures about 1 and 3/4 inches front face to back face, and the button is about 1 and 1/4 inches in diameter. The pawl seems to move up and down about 3/8 inch when the key is turned 180 degrees.
Here are the pictures of it:

Paul FitzGerald confirms that the measurments of 1 and 1/4 inch button diameter and 1 and 3/4 face to face match his original lock.
November 2018:
The Henry Ford Museum put up some drawings regarding the GPW, one of which is for the coding/bitting of the H700 key that is correct for this lock. 
To rekey for H700, first remove cylinder (If you don’t have a key for the current code, remove the glove box door, and you should be able to pick this lock on the bench with a little time and patience and the right picks, just take your time, after getting the wafers pushed up to the right level turn it further clockwise to the tumbler removal position do not try to force it in any way, or to drill it.)
Then find a set of “wafters” (a.k.a. tumblers) (Perhaps tear down other B&S auto locks to get them) that all extend beyond the cylinder when the H700 key is inserted, or better yet, a set of new “uncoded” wafers (Perhaps from an NOS uncoded 1930-60 vintage B&S lock for some other car off eBay), and then file down flush on top and bottom of the cylinder while the H700 key is in the lock as follows:
Sep 27, 2019 update:
There has been some discussion on G503 saying that the B&S made Chevrolet glove box lock cylinder uses a different key blank, and can not be easily rekeyed to H700 by filing the tumblers alone. I had no problem doing this, as discussed above, and was wondering if there is a difference.
After looking at both NOS B&S H700 keys and cylinders, and the NOS B&S Chevrolet key and cylinder I have, I found: The Chevrolet B&S key would NOT go into an B&S H700 ignition lock cylinder, and would NOT go into an NOS H700 keyed Independent Lock Co. spare tire lock either. I find that a standard NOS B&S made H700 key (per the GP3685 drawing above) WILL go into the Chevrolet glove box lock, but that the key that came with the NOS Independent Lock Co. H700 spare tire lock will go in, but will not turn.
Therefore I believe that there may be a small difference, but that B&S made H700 keys (per the GP3685 drawing above) have slightly wider grooves, which seem to accommodate the slightly different B&S Chevrolet cylinder. When a B&S made H700 key is in the B&S Chevrolet glove box it does seem to be a good fit, meaning some of the edges and grooves do line up correctly.
Here are some pictures of these keys, top is the NOS B&S made GM/Chevrolet key that came with the glove box lock, middle one is a NOS B&S H700, and the bottom one came with my NOS Independent Lock Co. spare tire lock.
I believe if you use commonly available NOS H700 keys made to the above GP3685 drawing, it will work in the GM/Chevrolet glove box lock, after you rekey/file the tumblers to the H700 “bitting”.
Here is a picture of an NOS B&S H700 key in my GM/Chevrolet lock, turned half way, to show it does fit and work. This key goes in and out smoothly, and after adjusting (filing) the tumblers (wafers) only to match the H700 bitting, it works smoothly, and with no slop.
