Saving Old Seagulls

Just got a WSPCL----NN7 as a parts motor, it has a siba recoil start and plastic tank on it. Were these available on this motor or should I assume they were refits?

Plastic tank came rather later than 1977, so probably that's a replacement.

The Siba recoil start is likely an addition too. These were available later as an add-on accessory from British Seagull in the 'completely enclosed' format - ie the samew shape on top as seen on the later adverts, and carried on through the QB series.

If the recoil is one of those in a steel tube frame it didn't come from British Seagull, who regarded them as unnecessary, and refused to have anything to do with them on safety grounds.

Thanks Charles, It is totally enclosed, I assume the ignition wouldn't be a Mkll? Phil
