Oil hose adaptor 65-2252

[RogerSB]

I'm looking to have some braided hoses made up for my 1960 Golden Flash oil return pipe (one from the crankcase adaptor to the filter in and one from filter out to oil tank).

Can anyone confirm that the threads on the original armoured fittings are 1/4 BSP?

Also, as a matter of interest, does anybody know what the threads are that screws into the crankcase on the adaptor?

Pics attached.

Thank in anticipation, Roger.

If it's any use to anyone I've found out it's 3/8" BSF into the crankcase and 1/4" BSP to oil hose.

(Edit) I'm surprised nobody knew on here.

We all knew but we thought it would be good for your self confidence to let you answer.

I knew there would be a good reason for it
