seeking greasers caps (hats)
 

Like those the old engine men used to wear when oiling underneath the machine.

Even throw away paper ones would do.

I've tried Dickies and Ebay but can't seem to find the right thing.

Thanks

Give Tony Wood a shout from Walker Midgley, he's Flywheel on here. I'm sure he had something similar he used to take with him to rallies. Ted.

Railway style grease tops? Tony Wood sells them.
