Thanks, I think....
I just want to show that it is possible to replicate a casting without measurements based on pictures and known adjacent items to create a reasonable stand-in. This is especially useful if your recreation options are limited. I have a pdf drawing of the later Type B wheel but that has flush spokes attaching at the bottom of the perfectly round ring and appears to be slightly larger. I do however think that I'm a little oversized on the Type A (horizontal) diameter but was unable to roll the ring any tighter on my bender without modification. The vertical Type B shown was also used on the A Mancha but I'm not certain if that particular example was a replacement part or factory fitted, however it is still way better result in looks over the casting pattern that our Foundry had used.
