Congratulations on your Two-Spool! I'm happy for you that you got it. From what I've been able to determine, and my knowledge is extremely limited, the Two Spool Machines are a little rare! I know you sure don't want to lose the thread canister for the bottom spool. I saw one on e-bay a while back with a starting bid (or reserve) of $350! It makes you wonder what kind of wacky weed they're smokin'!
