According to that site, it's a '59
ED7B matches Engine Prefix and Engine Sequence 101x matches 1069

And there is not a lot older than me.
Nicola keeps reminding me that in 2 years I can start adding SAGA to my favourites on the computer.
Based on just the engine number, off this link, it seems to be a 1959 model.

Sex and Games for the aged? LOL
Quick update on the frame number "saga".
Took the number board off the bike tonight, and scraped the headstock paint off on all sides.
No numbers, and no apparant signs of numbers being removed at any point.
Any further suggestions, theories ?
I wonder if it is not some kind of a "Bitsa" bike.

Well I'm not too sure about those dips in the frame under the seat Grizz, can't remember them on a Bantam frame and none of the pictures seems to show them 
Try looking for the frame number round where the lug is for the front engine mount....

You're not alone May be a replacement frame, or a bastardised effort for trials, who knows At least you know the engine's age.Good luck with it anyway

Pic taken next to measuring tape for clarity.
Shock - Spring: 8" Long, 2" Diameter.
Shock Body total length - 13"
Body mounting hole centres @ 11 3/4"
Shock mounting points - 1" wide with rubber bushes inside.
These are a couple of inches longer which should give a bit more travel before the tyre hits your mudguard after landing a double back somersault

Looks to be 100% better condition than the ones on the bike.
Do you think one would be able to "force" the extra 2 1/2 inches into the space between mounting points ?
I suspect it is do-able.
Your bike has a swinging arm mate
OK, you win.
No idea where my eyes and brain were focussed.
D'ya know ... I'm gonna enjoy this thread Grizz

I'm looking forward to when Grizz discovers the clutch plates have stuck together

Or the con rod, big end and crank are as are one
Well I guess that if Marco Polo had known what was in store he would have stayed at home in front of the fire with his feet up

I suspect there will be much wailing and gritting of teeth from my garage in time to come.
Popcorn time for those of you following my fun and games with the "Bitsa Bantam"
Spent a few hours in the garage today.
The mystery of the frame number that is not there, continues.
Checked lugs, under tank, and inderneatht the frame.
At this point the ideal would probably be to have some very clever BSA specialist/anorak check over the frame, to see where the number that I cannot seem to find, is hiding.
After another 24 hours with some diesel on the plug, it still would not budge, so "Plan B" was set in motion.
Again, not all plain sailing, as one of the nuts would not release at the top, but was quite happy to come out the bottom end. Later after a few hours in diesel, and screwed into the vice, it continued to have a mind of its own, so now it is back in the diesel bath along with the head and chain.
With the head pulled off, I was greeted by a load of crumbly dirt on top of the piston, and some rust on the bore.
Plug seemed to be part of the whole thing from the inside as well, so is now sat in the diesel bath with diesel all over the inner surface.
The rest does not look much better, and WD40 and Diesel , helped along with some force from a 5 pound hammer and a piece of wood on top of the piston , has seen no change in position of the piston.
While I was at it, I also removed the carburetor to get some WD40 inside the head under the piston, in case it helps.
Got the throttle and controls off, with some more wood and hammer action, throttle was really rusted to the handlebar, and the inside is badly pitted, with about 2/3 of it rusted. I would think that new handlebars may be in order if I can get the engine fired up, and if the gearbox plays along.
Once the seat was off, the bend in the rear subframe became more visible, also showing a weld on the left side, to the right of the photo. Not sure why it had been welded, but seems a neat enough job.
The parts removed today in neat order, as I need to work that way, so as to be able to reverse the process at some point when rebuilding it all.
Note all the loose rust from the tank, seems there is a lot of corrosion pretty much everywhere on this bike.
Parked up the bike at this point with the diesel topped up on the piston.
Lets hope it goes somewhere in the next few days (I mean downward)
