I also sent Guy a note a couple of days ago and no response as of yet.

Lagopus, Do you know if the book covers a single shot break open hammerless gun. I have one marked Midland Gun Co. LTD, B'ham, England. It is a single shot, extractor 12 Ga, with cocking indicator, chrome lined bore and choked Mod chambered in 3". Gun has an extension on the trigger guard to open it. It was probably built in the last 10-15 years.

Thanks,
