Very Rare No-Number original exhaust pipes

[cfairweather]

If you have a sandcast or know anyone that has one, they should know about some pipes that I have on eBay right now. I did not realize just how rare these pipes were until after I listed them. Two of the pipes, #1 an #4 are original "No-No" (No number stamped on them) pipes. It seems that 1000-7500 (probably about 4000) sets of these were produced.
