Saving Old Seagulls

No stainless or plain steel are fine.

I'd suggest looking on ebay for the correct carb, as setting up the one you have might be tricky. To attach photos see this screenshot:

I have the same lathe, in the UK several sellers market them, mine is a Chinese made Chester lathe. Works well for small items.

Yes, I can imagine somebody producing those on a capstan lathe, couple of minutes for each one!

I made one out of nickel brake pipe on an earlier project, and bent it using a hand held Bending tool. I’ve also made a SD pipe the same way,out of copper tube.

You have made a great job, the attention to detail sets a standard for all. Love those correct gearbox cap brass bolts

What do we know about the changeover of production to engines being made in Poole?

It would be great to know more about the transition from John Marston Ltd to the new British Seagull company. For example when did the actual transition take place, when did production move etc?

Didn’t the OP/ON have the top rudder fitting that was a clamp around the exhaust?

I might be interested, I have a couple of mallards myself. How much are you asking? Also are they all non machined?

Sorry you are right. I forgot about that

There’s an OA just appeared too, with a cracked block that seems to have lost its cooling fins. It’s also been flashed over with silver spray paint. Oh dear.

Can somebody let me have the outside diameter, wall thickness and overall length of a full length SD drive shaft tube please?

Yes, a big word of caution required for sure. The tiller mount seems to be missing, as it has some sort of frame bolted to the crankcase. So quite possibly new crankcases required. Also there are signs of oil coming from the gearbox cap, threads gone perhaps? Somebody will bid big money for this one...

Now relisted?

This one soon disappeared, I wondered how long before it vanished I wonder if it is a new number for the register?
