This is a question for those of you who have RRT2 gearboxes. Was a 1/4" stamp used for the 'T' on your gearbox, and does it have a serif font (i.e. with a base and vertical ticks at the ends of the crossbar, rather than the 'T' consisting of just two straight lines)? Every one I have seen has been like this.

FWIW my 1962 ARRT2 gearbox has a serif font (Roman) "T".

Very helpful. Thank you. As far as I can tell, even some of the same gearbox numbers and letters varied in size and came with and without serifs, but the "T" was a constant. I'm particularly interested if this is true for the RRT2.

But is the 'T' 1/4" tall and with a serif font?

My two. Odd the T is different. Both have RR gearing inside.

The top one came out of a race bike that was a bitsa that was raced in SE Asia. The bottom one came out of a GS that came direct from the factory and was raced around the UK.

Not to be rude, but who cares? Drag your feets back into the workshop and do some proper works on your bikes or take the bike out for a spin...

I prefer to mend my bikes or get out riding them, yes I know my bikes is not entierly original, but I like them and they are mine and they are all on the road...


best regards

I like to work on my bikes and take them out for a spin. However, that still leaves me time to care about other things, and one of those things that interests me is the font used for the 'T' stamped on a gearbox.

Having served an apprenticeship in British industry,..early 1960's.. and spent some time in the automotive transmissions manufacturing area,I doubt that,even if BSA had a tech. spec. for the font size,the assembly fitters would abide by it.The fitter probably used what he had in his tool kit.In the old British production lines "close enough" was typical.

I'm not saying you're wrong, but the composite picture shows the 'T' from an SCT2 (made only in 1957; for an A10), an ASCT (made only in 1962; for a Gold Star), and two Std from unknown models. I didn't take the time to move my 1963 Gold Star to where I could photograph its SCT, but the 'T' is the same on it. That's five identical 'T's on two models of BSAs made up to six years apart. For the apprentice to have used his own stamps for this over the 6-year period means the same guy was stamping numbers on models coming off different production lines, and he had to have been good enough not to have been fired, but bad enough not to have been promoted.



I've been interested in this for quite a while, and probably have looked at the 'T' on at least 20 bikes, but have never personally seen a font different than this one for the 'T'. I'm not saying different fonts couldn't have been used, but I'm interested in whether there might be other examples, especially for RRT2s (Boomer provided one, and we've been discussing it off-line).

p.s. next I suppose someone will tell me that he believes studying the font of a specific letter used on gearboxes of bikes made 50+ years ago by a company that long ago went bankrupt isn't one of the most compelling issues of the 21st century...

Apprentices worked a 5 year term .. 16 years of age to 21 years of age (indentured),they were then considered "journeymen".
My point was that the fitters may have had the "correct" stamps at some point,but, following loss or damage they used a "close enough" stamp.As journeymen we were moved to departments as required .. taking our own tools with us,no doubt fitters at BSA did the same.

I'm not questioning this at all. Even though at the time BSA had 5 or 6 separate assembly lines operating in parallel (I forget the number, and it's not worth the time to look it up), gearboxes were no doubt all produced separately on their own mini-assembly line. Certainly, the '57 SCT2 could have been one of the first gearboxes stamped by a given apprentice assigned to that line, and the '63 SCT one of the last before he was promoted -- jeez, what a horrible life that guy had, whacking a hammer countless times onto stamps, day after day, year after year, for 6 years...but, I digress -- but it's still of interest to me why I've seen only that particular 'T'.

In mulling the subject.. could it be that BSA used that style of font in acknowledgement of the Torrington bearings contained in the gearbox?...as opposed to Timken ... the Timken company name was spelled using a block T.. at least in Britain... at the time these gearboxes were made.ust a thought.

I know this is an old thread but all the gearboxes my father and I have had RR (RRT2) (SCT) DAY have all had the same size big T's with roman type serifs.
But the RR and SC DAY stamping have differed from plane stamps to ones with serifs aswell,
Also on the back of the inner sandwich plates above the raised part number is the stamped in part number (42-3083 or 42-3083). On the RR RRT2 SCT DAY type boxes we have had, this number has been serifed and always very lightly stamped in?? Sometimes hard to read? But these replica gearboxes always seem to have them heavily stamped in.
Not sure if any of that helps but I'm a bit of a gearbox pervert

Middle East,
Just to add to the discussion...this gearbox's history was unknown to me when it was bought in the late 80's. It sat unused until John Edwards rebuilt it to go in my bike, though all the right bits were there:

For a gearbox stamp these are much more likely to be factory original than the engine which of course has the incentive of adding value (I know the T also adds value but not to the same level as adding GS to a B33 set of cases). The factory would likely have only one assembly line for the gearbox but if it was run on more than one shift then the different shifts would lock away their tools so they knew they could find them at the start of their next shift. The stamps may have been locked away or left on the bench, if the T went missing (the guy with the key off sick?) then a runner would have been sent to the stores for a replacement T and I doubt the font would be specified, when the old one resurfaced they would have reverted to that one and restocked the replacement or stored it as a spare.
