102 ?

Post by cookie1 »

Hello ,

I received a new addition today , engine number SD1593P3 . Engine number would suggest a wartime 102 but it has finned cylinder head

Any thoughts ?

Cheers

If it has a finned head then, it has a Marston head fitted.

Hi
Thanks for that , the head is same as your picture . Is it possible this is an earlier head on a later Seagull or a factory built one ?

A later Marston heads will fit an SD, later on the 102 went to studs fitted to the head rather than studs fitted to the crank case.
Earlier head on a later Seagull, pretty much.

The very early 1942 ones had that B number. I call it a batch number but we don't know the relevance. May l pm you with a questionnaire so l can add your motor to the global SD register? TIA

Thanks for that , please send message I'll be happy to give any information I can . My initial aim was to save old and obscure motors from the scrap heap and hopefully restore some at a later date . I have 9 Seagulls here from little forty upwards and another 20 or so of ' other breeds ' all in various states . If anyone has anything odd for disposal please send a message , thanks .

As I mentioned earlier its a bit sorry . It looks like someone has started to replace exhaust at some stage but its not worked out .

It's a bit of a mixed bag of parts, but it's worth putting right, nice find.

Yes, well worth putting some time into for sure. A lot of original parts there.

Excellent. It has all the major parts intact. JM magneto with ali lid, steel tank with chrome bayonet cap, clutched gearbox. I like the replacement earlier cylinder. These are a tad longer than later longshaft seagulls hence replacement exhaust too short. Brass tube can be sourced. Does she have a tiller arm and throttle lever?

Thanks for the comments . What you see in the pictures is what I got although I do have some remnants of another early 102 which may help . Were these fitted with a steel tank as standard ?

Yep. All of them. The later ones have the groove where the end caps are attached.
