Thread Tension Assembly for Singer Models 66 & 99 - 17.4mm Barrel - With Release Pin

Thought I just needed a spring, but after more than a hundred years of operation decided to get whole assembly. I am glad I did, turns out my pin was 1/8" too short. My old 66 is stiching like new.

Its a little long for the machine but i made it work

Found a Free market place singer 99. Easy tension disc replacement and this machine runs perfectly. Accurate description of replacement tension disc, great price quick shipment. Thank you
