I'm likely on the wrong track looking into some of the parts origin earlier thinking British. Studebaker and Reo Motors parts found amongst it all.
GB150219 Washer
LV7/NEU GB150190, Fork
LV/NEU RA-170022, LV7/NEU FA-160381 Nut, LV7/NEU 150507 Carrier,
2-Gear Countershaft 3rd Speed, Rest of two crossed out Mfr's # SD66(56?), another marked LV7/NEU, GB-150170
LV7/NEU GB-150208 Rod Gearshift, LV7/NEU GB-151079 Washer, LV7/NEU GB-151073 Fork,
Reo Motors, Inc Part Number 667307 Group 1006, Bushing, Model 6x6
Studebaker Corp Part Number 667367, Model 6x4
There's more in the bottom of a drum to pull out yet but mostly more of the same I think.
(ps Thanks Terry for your help yesterday)
