What is this motor?

[mark2]

What is this motor? Retirement in full swing and I’ve started far too many projects, so whilst waiting I may as well start another, had this a long time and never found out what it is so anyone want to take a guess, I was going to build a run and jump on thing but my running days are over so maybe a look at thing instead.\ the cases and barrel flange are stamped with the same four digit number and I don’t think the carb is correct

That's a Quadrant engine. The inlet valve behind the cylinder and the side exhaust was an arrangement which I believe was peculiar to them.

I've seen the arrangement on machines from about 1911/12 in the press of the time, but it could well have gone on later than that.

The carburettor looks like a Brown and Barlow, which seems normal enough in itself. Not sure about the right-angle air intake, but I dare say that's detachable.

A reasonable number seem to have survived, which might mean that the engine number can be put into a sequence.
And there's a very knowledgeable marque specialist, but as far as I know he's not on email.

By the way - I'd suggest that this is too rare an engine to 'waste' in a 'bitza' project or have sat on a stand.

thankyou , did a goggle and it looks like your correct 1911/12 , made and still in the midlands , I wish I had more of the machine and I would not be interested in recreating the bike as it would take to long and would never cover the cost in final value  , will make a interesting talking ornament but that's about all as I have other bikes on the go , thanks again for helping https://www.google.co.uk/search?q=1911+quadrant&biw=1366&bih=611&source=lnms&tbm=isch&sa=X&ved=0CAYQ_AUoAWoVChMIncLmxbm8xwIVQboUCh1QhQGA#imgrc=d7wjAWVJrtueLM%3A

The carb looks more like a 20s one, as does the magneto.
As far as I can tell, the particular valve arrangement ran between 1910 and 1923 - I'd guess it's post-WWI (probably 1919 by the time manufacture recommenced) up to 1923.

If you send me a private message I dare say I can get a postal address for the marque specialist - he'd be able to identify the year and model, and might well know of someone who's spent years looking for of of these, so you could move it on to a good home, if it's too far down the list to be a realistic prospect for you.

The pilot-jet B&B and the (ML?) magneto are both later than the motor.

call to a dealer friend and I may have located a tank will see next week , I don't know why as I have decided to make a special type of single speed machine using the engine which looks quite good .\

[mark2]

can anyone date the mag ? may tell me more thanks \

As I mentioned, it looks like an M.L., probably late war - early 1920s. Type K1 was part of a universal code for magneto makers: K means "large size, 45mm spindle height, large taper", and 1 means single cylinder. No doubt a type M2 would be suits smaller motor, 35mm spindle height, small taper, 2 cylinder (180 degrees). KV large V twin etc.
