Nooky's Nuts have excellent product. I haven't tried them lately, but mostly, worldwide, postage to Australia has gone from reasonable (pre-covid) to prohibitive. So many things I can no longer source at a half-way reasonable price. What a pity!

Thanks for persevering! Very interesting.

It's a funny engine, depending on how you look at it either advanced (ohc) or primitive (oiling and other stuff). Somehow the the presence of a set of timing gears to get up to the back of the engine, but still needing a magneto chain from there, seems a bit weird. But interesting none-the-less.

Do you know anyone who needs the engine parts - they're probably available.

Here's some unusual bits: lumps of a 1920s overhead cam Matchless single, engine number L/R 1618

I don't think I know of a complete survivor in Australia, so I guess they're a bit rare? Or perhaps I don't know much about Matchlesses! Any interest?

(Edit: OK, there is at least one! https://club.shannons.com.au/club/bike-news/old-bikes/matchless-lr2-a-rare-beast/ )

Penrite Transoil 250. It's oil, it's really thick, and it comes with a tube in the cap to squeeze it into the box.

... it mostly used the same remote lever in a tank-side gate as the horizontal "Gen 2" (mid 1915 to 1919).

It didn't, actually: the Gen 3 has a Gen 3 lever. But no matter...

Up until 1923 all Albion gearboxes were "lightweight", to suit motors like the 269 Villiers and the 293 JAP. For 1923 Albion introduced the "featherweight" box, a 2-speeder for engines with "Max 2 h.p." - 200cc. It looked just like BF436 (the subject of this thread), but had a remote lever, so no lug on the box for the lever. I think that came about 1925, but you could get plain, clutch, and clutch+ks versions from the beginning.

So there were Albion boxes that looked just like BF436 from about 1925.

Thanks for all the info, 33d6. Fascinating. (Yeah, it's probably sad to be fascinated by Albion gearbox numbers.) I went back to the VMCC Register and I see less chaos now I get the B, BA, BAA thing. Boy they must have made a lot of gearboxes. Have you ever seen a guess at the total number?

Mixed in with the "usual" numbers there are prefixes like MON, but if you allow the possibility that (say) Monet Goyon might have been amongst the thousands of customers who used Albion gear boxes... it makes me worry less. I certainly don't intend to pursue the serial numbers further.

From my perspective, I'm specially interested in the veteran and early vintage end of things. I think I have the nailed the early progression, from the early "flat" boxes (with the main and lay shafts in the same plane) through to the first of the "vertical" boxes (with the shafts above one another), which seem to have started post WW1, and their various change lever configurations. I suspect the switch was pragmatic: the vertical boxes were shorter, and could be squeezed into frames designed as direct belt drive. At the Bendigo swap meet last year I saw a 2-speed Albion box that was labelled "Levis". I pointed out to the seller that the word Levis was not cast into the gearbox itself, but into an adaptor that sat atop the box to allow it to bolt straight into the single-speed Levis frame. Of course I had to get to the bottom of that puzzle when I got home - see below.

Deciphering the Albion gearbox numbering system is another thing altogether and isn't very helpful as you still have to deal with the slightly different versions of the same box which the numbering system doesn't seem to recognise.

OMG - I had a look at Albion gb numbers in the VMCC Register and quickly gave up. I could see no real pattern in the numbering, but I guess somewhere out there is/was someone who spent the time to figure it all out! Given Albion's involvement with bikes, mowers, and all manner of mechanical devices, I guess they made tens (hundreds?) of thousands of gearboxes in hundreds of different designs. But it certainly seems that the particular box we're discussing is indeed motorcycle, from the early 1930s.

There were many variants of Albion boxes! This is the 2-speed + clutch variant. In the 1931 catalogue for "Albion Midget Gear Boxes" this model (identical?) was referred to as the BJ. I know nothing, but maybe BF was an earlier model, say 1927?? In 1931 the EJ gave 3 speeds + clutch + ks.

Anyway, no reason it couldn't go into a bike from the 1920s, although Australian made stuff (for example, I'm thinking Waratah) tended to offer 2-speed no-clutch for a base model, or fancy 3-speed + clutch + ks. Although by 1927 maybe even the basic 2-speeder needed a clutch.

Also, chain final drive was taking over from belt around 1927.
