The Midland Gun Company had a factory in Birmingham and mostly provided trade guns to provincial stores. Most of their output was inexpensive. Lots of hammer guns and boxlock non-ejectors.

They did make guns under their own name and their better grade was called the 'Demon' and had a distinctive buttplate resplendent with well-hung demonic figure. Later models had the little chap emasculated to save the blushes of the prudish.

As ever, judge the individual gun and forget what the name says.
