2 on stock
S/AC4/3 4mm scale Sprat & Winkle Mk3 autocoupling trial pack

This starter pack contains a fret of 8 AC4/3 delayed action autocouplings for use on 4mm scale layouts. They have also been successfully used in 0-16.5.

Also included are lenghts of BW brass wire, NSW4 nickel silver wire, and of SIW4 soft iron wire, and one 4MAG permanent magnet.

The recommended minimum radius curve for these couplings in 4mm scale is 2ft. For tighter curves, use the MP4 mounting plates. They also have the added advantage of making the couplings easier to fit.

The actual size of the full size fret is 92½ x 144mm; it is etched in 0.015" brass. One quarter of the fret is included in this pack. Each coupling is 32mm long and 10½mm wide. The magnet is 25mm long, 7½mm wide and 4mm deep.
