Hi all,
I am in NZ
I have just bought a decrepid 28" BSA to eventually do up. why? As a kid, my 1st bike was a second-hand 3/4 frame 26" BSA Starflyer which is still the best present I ever had. At age 11 I broke the rear axle, so bought a spare from my local bike shop and pulled apart the SA 3 speed hub... ball bearings everywhere, but I got it all back together again and it worked for years until I cracked the frame at the head tube because I was a large 70 kg teenager! I also owned a .308 BSA Majestic Featherweight rifle for a while...

Anyway, I bought this bicycle, which I guess is about 1920. It has a DreiGang Torpedo toptube shifter which is broken, and an unusual hub which I assume is the same brand.
It has a 40 spoke rear wheel and 32 spoke front wheel. Both rims are rusted through so they have to go. I dont know whether the hub is usuable or worn.
The hub has a coaster brake and 2 oil filler thingies, both with their little lids still attached.
The frame serial number is 5765, only 4 digits, but I cannot find out anything about early BSA serial numbers. the mudguards are different - the front semi-circular section with a red pinstripe, the rear a more flattened section, plain black.
At first I thought the handle bar to be a later type, but it is quite old with the same diameter throughout.

I thought about converting to modern 700 wheels and a Shimano Nexus 8 speed hub, but this is a bit "off" really.

So, can anyone help me date this bike, offer suggestions for doing it up or otherwise? I think it is too rusty to use unrestored, and will probably paint it black and get some new BSA transfers.
Where the Hell can I get 40 hole and 32 hole 28" rims from?

All help appreciated, Al, NZ
