Metal Coupler Covers, HO Scale, by Scientific, Pack of 20

Work great

Handy to have

I acquire a lot of used engines and rolling stock from various places, which means couplers and associated parts are missing. I have used enough of these gems to feel the need to order more because they have kept my rolling stock rolling, and engines pulling.

Arther’s only

Works for Arthern BB kits. Not tried on other brands.!
