Industrial wheel centres

This set of 4 pairs of wheel centre bosses, etched in thin brass are designed to be used with 4mm scale Romford style wheels and axles, and are simply glued over the axle nut with a small drop of gel superglue.

Specifically designed to be easy to fit, they are sized to cover just the nut making removal at a later date a case of popping them off. Their small size suits smaller diameter wheels common on industrial models, but also suitable for any small steam and diesel models.
