Another one parted out...Looking For Milsurps Members Help

Update on my quest:
The buyer of the push safety sent me a message regarding seeing a J.U. stamped trigger listed on the sellers page, the same day the other parts from the IBM were posted. Using auction site advanced search, I found it.

Also of note: The lot/tracking number seller used on both auction sites for the IBM parts was "#5521".

IBM integrated ~37,500 triggers from Underwood between 9-43 & 11-43. The shipments, authorizations and or requests were documented. WarBaby! pg. 483
