TRW,I have a pre 1900 Midland catalogue[71 pages], Address is:
Midland Gun Co;
Demon Gun Works, Bath Street, Birmingham.
However Bath Street has been ruled out and Veesey Street added!
In the 1950's I was in the Midland shop,then located at Whittal & Bath Street. At that time they were making high grade single barrel guns for the African market, England having banned the sale of doubles in what was a troubled time for the British colonies.
The main selling points in the catalogue praised their ,"Solid body hammer guns and The best gun ever offered by anyone at the price listed regardless of type!"
This is a classic Victorian catalogue one that I have thought of having reprinted.
