12 wood spokes with 4 lugs could be a LOT of 1929-1930 car wheels. Looks like Dodge, Plymouth, Chrysler or DeSoto. What do the hubcaps say on them?
I have no idea what the caps say I just found the picture in here. Trying to find out what they are have someone wanting a set.
I've a set of late 20's Dodge, and a set off of a 31/32 Dodge. The rears require a tapered axle, both front sets I have use different sized bearings. I think (IIRC) the tapers on the rears are the same. Just something for your friend to think about if he's looking to adapt them to fit something they weren't intended for.
