Hi Mike
Thanks for your help! It's in the log book as 1938. I will see if I can have a look for a code on the engine, the radiator might be in the way a bit. And I know it's been in a barn for a long time, that's helped keep it in good condition! There is not an oil tank that I'm aware of on the vehicle, which is why I thought it was a normal wet sump engine. Maybe it is not the crossley fwd model after all? It all seems a bit mixed up!
Regards
Louie
