Here is an example of the confusion for A48:
VOC Spares & Vincent spares parts list describe it as "1/4 BSP banjo
Series A alternative list describes A48 as "Banjo Union 5/16" bore pipe"
Both of the above are the same part with the same dimensions and fit a 1/4 BSP banjo bolt and also fit a rubber hose pipe with 5/16" internal bore.

Hi Simon and folks,
well, I think that A48/1 might not exist- as a number!
Rather it should be numbered A29.
Just to be clear, we are talking about the hot stamped brass 1/4 BSP banjo, but one with a 3/8" OD pipe for use on the pump feed of the Series A.
I have seen a works drawing for the post-war pump feed pipe for the 500cc [A66/2AS] and this shows part A29 Banjo "Sweated" into the feed pipe.
I think this is the very same hot stamped brass banjo with the 3/8" pipe, which I think is a "left over" Series A part.
What fun.
regards, Delboy.
Possibly later they made a simpler dedicated turned part to fit the post-war pump feed pipe.
