Vintage Multitool Driver

[lzenglish]

My "Semi-Automatic, 6 Bit Drum Driver", No Makers Name, Patent# 4572038, Made in USA, 1980s. Operation: Line up both white line marks on handle and shaft, pull back, turn bit drum to desired bit, and push in to load it. Note...Bits do not fall out like allot of other drivers do. eBay Find. "Love The Creative Idea Behind it, as well as the Quality of it" ! Also, drive shaft is free turning, as you hold the drum in place. Just another Gimmick Tool for my Gimmick Tools Collection.

Patent #4572038....
