Ham Radio Variable Roller Inductor Coil Capacitor Antenna Tuning Thing DETAILS

Item was in a large lot of ham radio stuff I picked up. PLEASE SEE ALL PHOTOS PROVIDED. I did research the item and I'm pretty sure it's apart of a ham radio antenna tuning system.

The lot I picked up had a LOT of Collin's radio parts but I cannot confirm if this is apart of a Collin's radio. Any info is greatly appreciated! Item is listed as untested for parts obviously.

We have other ham radio stuff listed.
