Used one in the middle. I have a box of them. Aluminum this time. I didn't get pins or gaskets this time. Bare as is $20 each. Order em now I'll bring to Carlisle.
Yes. I used mother's aluminum and mag polish with some 0000 steel wool. They do come up much nicer. I'm sure if you could hold onto them on a good polish wheel you could get a mirror finish. I still have about 40 left at the moment.
If you want a set PM me for the address to send money order to. Price is $20 each and shipping up to 10 pieces is $8. First pic is an original in middle of four clones unpolished. Second pic has one polished by hand with the mother's and 0000 steel wool.
