Hi Folks, after 40 years of ownership I only today noticed some much smaller stampings under the engine number of my 51 Comet. "BMH" is stamped upside down on the crankcase under the engine number. Anyone able to enlighten me a to what this is about? Many thanks in advance

It possibly refers to foundry date code used by John Dale's. In which case the casting was made on 8th December 1949. It could also be a private stamping by a mechanic any time in the last 70-odd years, although Hillgate Motors, for example, usually decorated "right way up". Another possibility is an inspection stamp. These often appeared in a small circle.
Thanks for that info
If you blank off your engine number and just photograph the other numbers I could be more certain.
This is the number as it appears upside down under the engine number

That is a batch identity stamp by John Dale foundary in London Colney near St Albans, who cast most of the crankcases and some other components for Vincent.

Thanks for that information. Mystery solved. Will check my Rapide to see if it also has similar stamping
First letter is an "E", so 11th December 1949. Last digit means furnace no. 1. The stampings can occur in lots of different places, but this looks original to me.
