Hi Mike

Right up front... I'm not nearly as knowledgeable as you on Chev wheels.

I am lucky enough to have an original 1937 Sales Handbook for Commercial Cars and Trucks though.

Patrick may be referring to what Chev called a "short spoke" wheel used in 1937.

I scanned a page of the handbook showing an illustration of it, but it doesn't make clear if the illustration is of the standard 16" wheel or the optional 15" wheel, or represents both.

I wouldn't call this an artillery wheel, but some might.

@ole-olson Some who might call that an artillery wheel would be wrong. 1936 Passenger and 1/2 ton trucks used 17' artillery wheels. The "new for 1937" 3/4 ton trucks used a 15" artillery shells. These were continued through 1941, I think, on 3/4 ton models. 

The wheel illustrated in your 1937 Truck Data Book is the 1937-1938 passenger and 1/2 ton wheel with the center being riveted to the rim in 8 places, instead of the more common 4 places.

I don't think Chevy ever offered a 16" artillery wheel.

👍. 🙂

Just thinking that might be what they are looking for.

Came across this. 

What started our members request was that his wheels on his 37 Chevrolet 1/2 are the same that are on my 36 GMC, 16 inch Kelsey Hayes wheels, It may be that his wheels were replaced sometime in the past?  In any case GMC did have the 16 inch wheel in both 36 and 37.  Attached is a photo of my wheel .

@dunfire @ole-olson @north1941 As I mentioned before, 1936 Chevy 1/2 ton pickups had 17" artillery wheels. I have seen many pictures of Patricks truck and it never occurred to me that his wheels would be different. Perhaps the 16" wheel I have is like those. I just know that it has a larger hubcap opening than what was customary on Chevrolet for 1937-1938. A '37/'38 cap is about 9" across. A cap for my wheel would need to be about 1/2" bigger. The opening in the Chevy wheel is about 8" and the opening in the mystery wheel is about 8-1/2".

Patrick, let's have a measurement of your cap. Maybe we can all learn something here. I was told at one time that my wheel was for a Pontiac. Maybe GMC borrowed more than an engine from their GM sibling.

The opening on the rear of a NOS GMC hub cap is 7 1/2 inches   I bought a 16 wheel from Bruce Buguy about two years ago, black with a cream pinstrip, that he told that it came from a 36 Chevrolet Master, it was 6 lug and my hub cap fit it fine.  If you need, I can pull a hub cap off my spare and measure the distance on the opening of the wheel.

Chevrolet listed the stock wheels for 1937-38 Chevy cars and half ton trucks as "artillery".

They are different than the ones shown on Patrick's 1936GMC truck, but still called artillery, probably to distinguish from them wire spoke type wheels.

@headlighter @ole-olson Tom, I believe you are correct. That would be the wheel pictured in the info that Ole posted. My apology to Ole for doubting his assessment.
