Can you identify these hubs?

I've got this pair of spindles and hubs off a 47 ford I was going to use on my model A but I just realized that they are different. One hub mounts the drum on the backside and the other mounts the hub on the inside. The offset is exactly the same but the hubs are definately different. What is the difference between these? J.

 

Outside hub 46-48 ,inside hub 40-42

 

Outside hub 46-48. Inside hub may be F-1. Check the inside bearing dia. If bigger then it is F-1

 

If the indide hub was on a 47, and fit properly, it was a 40-42... the F-1 would have a bigger bearing as JE said..

 

Thanks! J.
