For sale is a lot of 18 Allison Collets, Round, Square & Hex, all dirty/tarnished from age/use, some have minor nicks. 1/4 round (a bit beat up). 9/16 round maybe for holding rough stock? Please view all pics as they are part of the description. I try to describe most of the items to the best of my ability, there are times when hubby inserts info onto a Post-It-Note that you will see in the pics. Please view all pics, as they are part of the description, this also applies to my “odds & ends” and “Lot of” items, as it is too time-consuming to describe each and every item. As long as I can package the tools safely, I’ll combine everything as cost-effective as possible. Please do NOT pay me until I send you a combined invoice (if applicable). We don’t go to the post office daily!
