Creeper Casters Wanted - FOUND!

[J.A.F.E.]

I know it's a long shot but I need an old fashioned creeper caster preferably the plastic kind. I can buy new metal ones from Whiteside who made the creeper originally but I like the way the plastic ones roll better. I've had this creeper a long time and I do have another but I really like this one and would like to keep it in service.

If you have any I'll buy as many as you want to sell.

Thank you.
