Saving Old Seagulls

Found this one on Ebay last night, only up the road, a buy now for Forty quid, so did I do good?
Not seen this type of long range tank before, obviously original, even though I keep thinking of B&S.

Hi Keith, I think you did a good buy.

What's the serial number? Must be a 1946 model.

Is the bakelite sparkplug cap an original KLG?

More pics?

Jan

Sure it was a good buy, why not? Some more parts and you have an original motor!

Looks like it Jan, cap could be worth £40, well done Keith.

Can't go wrong at £40! Nice one.

Your jesting H-A, one on the motor and one on my computer desk.
I think its a 46-47 motor, SD12685.
You can tell me what's right, or wrong.
It has good compression and spark.

Not joking, the vintage bike guys pay top dollar for those, and the short Champion ones.

P.S. Who bought the OA bits that were on the bay last night, "Uncle sticky" is breaking one by the looks of it.

KEITH

you beat me to it?
i should have hit the "buy it now" button much earlier!

yes indeed, interesting long range tank.
might be good for spares though!

i might know somebody with a steel tank and bayonet cap for that as well

It's covered on every bolt in red hematite gasket sealant, it's all over the place, the prop is knackered but I have them, I think I have enough parts to put it right. we will see.
The ignition has the old style points and works, but I may put a coolie hat on it, as I think its what it should have had on it.
Thanks for the offer, but I have a tank that will work and some caps about .

Keith,

I think the flywheel on your motor is correct for the time period.

Can you find any date stamp on the flywheel?

The magneto base plate must be different comparing a SD Villiers magneto and a MK I magneto.

I've got the same ignition set up on a 1947 AC model.

Jan

I don't know if it means anything to you.

Jan did villiers produce these flywheels before 1947?

I think Jan is right, a very late SD could well have crossed over with early post war C and D engines, with the flat topped magneto and screw and locknut points. Most SDPs of that period seem to have the flat top magneto too. However we have yet to get any definitive evidence to confirm, only theories!

1946 must have been a case of finishing the ministry orders as well as introducing the new post war models, how will we ever get to the bottom of it!

I've checked my early AC model and found 511/4291 (serial number?) and 3/7 (date?) stamped on the flywheel.

Charles, I don't know but it looks all original with the old style pill box, magneto baseplate, small rope pulley, plain cover and dome nut.
