I bought them for £1 from ebay seller gk24Sailor. He has an advert for other bits currently see 273178962463, not the bit you need but at least you can message him. Based in Andover.
His part number 68-0588. Hope this helps. Colin.

Hi,
    They are:

Part No. 68-0588   6mm x 10mm   or  1/4" x 3/8" or BS010

The best you can buy for this application will be FKM (FPM, viton/fluorel).

I got mine from:

Eastern Seals (UK) Ltd
Unit 3 Sovereign Business Park
Jubilee Industrial Estate
Ashington,
Northumberland, NE63 8UG, UK


Best wishes...

Why mess about with unknown sellers on ebay? All of the dealers who advertise in The Star sell these for pence. I needed some recently, called Andy at Kidderminster Motorcycles and they arrived with the postman the next day.
Just a thought!

Hi,
    I purchased 134 rings for £19.24 delivered. It worked out about 20 sets for the A65/A50.

Rev counter drive
Oil manifold
PRV
Oil tank drain plug
Oil pump
Gearbox drain plug

You will need BS010 (equ 6.1X1.6mm), BS014, BS020, BS016 AND BS008

Cheaper than buying individually via a BSA parts supplier.

Best wishes...

Hi,
    No, 3 branch is o ring is part number 68-0588, 1966 is 68-0598.

The 3 branch is recommended as a upgrade in the BSA service sheets, I've always heeded the recommendation and fitted the 3 branch as it improves the oil feed to the head.

Best wishes...
