Chester date mark query

Hi
I’m having trouble identifying marks on silver cigarette case.
So far I think it is Stirling silver, Chester , maker EJ Trevitt (who I believe were working 1900- 1935), but the date mark does not seem to match any examples I have looked at. It appears to be a B with a tail to the bottom left. A date in 1920-30s would match family history.
I’m not sure if I have added the photo correctly.
Thank you

Chester’s date letter cycle from 1926 to 1950 used an archaic set of letters. The letter on your cigarette case is actually “h” for the assay year 1933/34. The full set can be seen on my silvermakersmarks web site at Chester Date Letters - click through on the required part of the table.

Thank you for your help.
