Todays estate sale buys. Need ID help on 2 items

[NJ Marty]

Was the last day but there was still a lot of stuff to get. Got this and more (5 more boxes like these full) for $75. NOS light bulbs, flood lights and used radio and amp tubes. Also a mix of everything. I do need help on the last 2 items. The GS ssupercharger thing and the other item on the brown box with the saw looking attachment. They have got me stumped. ANY help on these is greatly appreciated, Thanks

Nice buys, maybe you can ask about your supercharger part on this forum:

All I could find on Jordan Services was that they were a radio shop and that W.E. Jordan collected books. This ad was from the New York Post dated 1939. I found several others like it too. Earlier in the century there was a motorcycle shop at that adress as well, so that supercharger may well be from around 1909-1915.

C.L. Williams was a motorcycle shop at that address, then a few later I turned up a Carl W. Bush Co. that was also a bike shop.
