Yes, confirmed, the ones on the left are all pipe taps. I used a scrap of 1-1/4" black iron pipe I had from a project a little while ago, and it's an exact match. I didn't realize the threads per inch were the same across pipe sizes, I thought they varried like bolts, but I guess. NPT should have given me that clue :P
Anywho, if anyone is interested, I'll do $10/tap +shipping. $15 for the long ones. Though I think I'll keep one of the 1-1/4" taps, as I like using that size pipe for welding projects...
