Bishop Self Propelled 25 pdr

[Larry Hayward]

Can anyone confirm which Royal Artillery Regiments (and their Batteries) used the 'Bishop' Self propelled 25 pdr (based on the Valentine tank) in Sicily and on the Italian mainland in 1943.

I have a reference to 142 (SP) Field Regt RA but have also seen 143 Regt RA mentioned for some of the same commonly published pictures and wonder whether this is a typo error

I don't think many were made so I doubt that many units had them.

Thanks
