Just picked this up at an antique shop for $4 (!). Can you tell me if these jaws are the the large jaws or the smaller jaws? What are the chances of finding/buying the other set of jaws? Before and after clean-up photos below.

Thanks. Al.

great buy - the puller is still available from Snap-on but has a list of $175.00. Looking at your picture i think that you have the large jaws. Jaws are available from Snap-on A78-3 for large @ $16.90 each and A78-4 for small @ $16.05 each.
