WW1 cancellations

[Abbottc]

Does anyone know where a WW1 "dumb cancellation" with the letters "BM" may have been posted ?

Not something I know anything about, but have you thought about contacting the Imperial War Museum?

Below is a link to their contacts page:-

When you get to this section - Which branch does your enquiry relate to? - Choose London
                                             What type of enquiry? - Choose question
                                             What is your enquiry about? - Choose Other General Enquiry

You then carry on and explain what you would like to know.

I've no idea whether they will be able to assist you but it's worth a try.  Hopefully they can suggest where you need to look if they can't help.

Or try a Philately website, there are philatelists who specialise in wartime cancellations.
