A few different Eley or Eley Brothers marked alarm gun designs have been seen over the years. They are primarily brass in construction and were meant to be used as alarm guns rather than lethal weapons as it is not proofed to fire projectile. This one has a rifled octagonal barrel inserted into a brass frame marked "ELEY BROTHERS LTD./LONDON" on top and with a brass mounting plate on the bottom. The firing bolt unthreads from the frame for loading and has a pin marked "ELEY BROS." on the chain.

Fine with aged patina on the brass, gray and brown patina and minor oxidation/pitting on the steel, and general mild wear. Mechanically fine.

This trap gun was meant as a blank firing an alarm gun, as it is not proofed to fire projectile, and has a screw-off smoothbore barrel and "ELEY-BIRMINGHAM" marked action with a three-hole mounting plate.

Fine with aged patina. Mechanically fine.
