Apparently some of the reproduction stabilizers (where available) can be unreliable, so here is an original Smith's BR1309/00 voltage stabilizer that I believe was used on some old Mini's, Morris Minors etc - but please double check exact fitment. Casing has been lightly blasted and lacquered to prevent rusting. Item has been tested/calibrated using original Smiths equipment so I can confirm it works correctly. Unlike some reproduction items this unit will work on negative or positive earthed vehicles.
