I made some of this spacers to Sweden hotrodders last year.
This is 32 spindles to Lincoln backingplates ( I think 42/48 ) no udea of whsg drum,
I had the 39/40 spindles and Lincoln 41 backingplate/drum ( like that flat look )
I seen Spencer in 1950’s used the 39 deep backingplates.
On pictures text say 41 Lincoln but thats not correct.
