This car

has just turned up on ebay. I had totally forgotten about this connection.
It appears that the 12 was supplied to and bodied by Sizaire-Berwick, fitted with a different radiator and marketed as the Sizaire-Berwick 13/26. The Austin 20 was given similar treatment and marketed as the Sizaire-Berwick 23/46. Have a look at this article published in Motor Sport Magazine July 1957
https://www.motorsportmagazine.com/arch ... he-sizaire
and Bob Wyatt's The Austin 1905-52 pages 78 onwards.
We (re-)learn something new every day!
