Not a No. 4??

[Guest]

I aquired a block and hammer that was supposed to be for a No.4 Rolling Block. Unfortunatly, they are not. They are very close and almost identical in size and shape but have a few important differences. The main ones are the block does not have a split for the extractor to fit in and the hammer does not have the spring roller. Does anyone have any idea what these might go to? I can e-mail pictures if that will help. I'm at fbparr@alltel.net.
