Odd vehicle related stuff

[mingoman]

This is something salesmen from Sunnen Honing Machines from St Louis gave out years ago to demonstrate how accurate their machines were. You can't pull the thing apart with the rubber stopper in, but take it out and it comes out easily.
I'm not sure, but think this is from the early 60's.
Anyone ever see one?
What odd stuff do you have?

That is an interesting find and a good way for the company to show their precision. I haven’t seen one before.

Hoping others will chime in. While I don’t think it is odd, I do have a diagnostic oscilloscope roll around piece of equipment by Sun, guessing from the 1940’s. It came from a Chevrolet dealership that closed in 1974 and I picked it up for $5 at auction about 15 years ago.

Also picked up a complete strobe light spin balancer for balancing wheels on the vehicle. It uses a 220v motor to spin non drive wheels. Paid $10 for it at an auction at a Ford dealership closing years ago. No one else knew what it was.

I’ll get some pictures this week.
