Its has a 5x5 pattern.

Someone else said it was a early 50's Chevy also.

Still in the process of taking it apart to clean it and hopefully I will come across some numbers or letters on it. If so I will post those.

It measures 50" center to center between the kingpins.

Any one know of a good way to free the shoe from the drums. Got one side broke lose but the other side wants to be a bear so I am soaking it in WD40 over night and hopefully will get it seperated tomorrow night.

Thanks for all the replies
