There are so many anonymous photographs of brass bands, most without any features to help identification. Here is one such British band – but there is a clue on the drum. It states “United Brass Band”, and above that is a very indistinct word. I have blown it up as much as possible, and open it up to your suggestions! A quick look in my database did not give any obvious contenders.
However it does look like “Bolton”, but I think this is not Bolton Lancashire, but probably the Wath and Bolton United Band, from Wath-on-Dearne, active in 1891 through into the early 1900’s. This would probably fit with the fact that some other wording (perhaps “Wath and”) would have been above the crest or insignia on the centre of the drum.
There is no reference to a “Bolton United Band” from Lancashire that I am aware of.
