Okay wheel experts, I need your help!. I bought these wheels off eBay thinking they were Ruttman Spyder wheels but they aren't. The seller listed them as AZUSA Astro wheels but they aren't. Both the original Ruttman wheels and the AZUSA Astro wheels have an inner and outer lip on the outer portion of the wheel. The seller had sold a set previously with the complete drum brake assembly as AZUSA Astro Barris Super Stocker wheels. That narrows it down a bit but who made them?, are there other makes/models that used them?. I am not the only one who has thought these are Ruttman wheels as I have seen them sold before as such. They are 6" dia. by 4" wide and have a little ridge around the bolt holes where the sprocket attaches if that helps. The first picture is of an actual Ruttman wheel, the second an AZUSA Astro and the third is of the drive wheel from the set I bought.
