TR2/3/3A Wheel Identification Help Please

The TR3 that I am working on has 60 spoke 15" diameter wheels, but they are 7" wide which appears to be wider than the stock 60 spoke 15" which I measure at 5 3/4" from edge to edge. The 7" wide wheels also seem to be a different off set. See pictures. The Red ones are the currently installed wheels and the gray one is spare. You can see an inch of difference in the offset.

My question is, can anyone give me a possible identification of who might have made these 7" wheels. I need to replace one that has worn splines.

Take a tire off and look on the inside of the rim. If you're luck you'll see a number similar to this: 6Jx15 ET30. That one is on a Jag wheel. If you find a number, you can use it for a replacement wheel.

Tom,
Thanks. I need to update this anyway. I was measuring from from the rim edges instead at the bead flange. I have also figured out these are 72 spoke wheels and the width of the wheel is something in the order of 5.75". Looking at the Dayton wheel web page there are TR250 and TR-6 wheels that are 15x6 that are 72 spoke wheels. Would TR 250 or TR-6 wire wheels have the same spline/hub size as a TR3? I have looked at several other wheels now and see where they are identified on the inside of the rim. I may resort to dismounting the tire.

Ok, to take this a step further, I did have the tire and tube removed and did indeed find more clues. In the very center section I found the following stamped - RM 7A 5 1/2 K 15N, Made in England and a D like the Dunlap logo. Seemed straight forward enough. I also found hand stamped into the wheel D457C. If you do a google search on that, it pops up a Dayton wire wheel for a TR250 or TR6 which is a 15 x 6 wire wheel with 72 spokes. This wheel measures 5 1/2" just like the first stamping showed. I settled on a 72 spoke, 15 x 5 1/2 wire wheel from Moss. We'll see how they match up and I'll update this for (hopefully) the last time.

Hand stamped? People do make mistakes and yours doesn't seem to be 6 inch. It will be interesting to see what you get.

Tom,
I said hand stamped because it looked like someone used a set of punches to put the dayton part number on the rim as opposed to the size information in the center of the rim which is typical of all the other wheels I've seen.

Ok, I can close this one out. The 15 x 5 1/2 72 spoke wheel I received from Moss seems to be exactly what I need. Now all I have to do is ruff the paint up, or get it blasted and paint it to match the wheel shown in #1.

Bump. Forgot to add the picture.
