Jerry, William Powells still exist. The moved a few years ago from Birmingham to near Banbury in Oxfordshire. The should be easily traced on the web. They made these actions for a number of other 'Gunmakers'. I was looking at one by Maleham very recently.

James, a Gunsmith friend of mine (sadly recently deceased) owned the name to Barratt of Burton-on-Trent and also the other Burton gun firm of Coltman. Sadly the records did not exist. Burton is only a few miles from me and quite a few Barratts turn up. I have seen a number of Barratt/Powell lift levers. Interesting and collectable guns. Lagopus.....
