Having had dealings with the Birmingham Proof House over many years I can assure you all that the old two rule system applies .
Rule 1 the Proof House is always right .
Rule 2 If shown they could be in error , see rule one .
Joke it may be but errors have/do and will occur in both London and Birmingham , incorrectly marked nominal bore sizes or chamber lengths for example .Date stamps being made with reversed letters are far less important than these .Interesting as it may be to collectors and enthusiast .
