I was given a very interesting martini firearm today and need some help to identify calibre, bore ect.
Martini action simular to 577/450 or 303.
Barrel length is 37 inches.
Rifling is a very slow twist of about 1 in 36.
A 20 gauge shotgun cartrige fits into the breech..
A 577 case is a very sloppy fit
No brand or makers name.
Barrel stamped :-WR H T , BR 20 WD.
Serial number under sight is 1032 R.
Brass butt plate and nose cap.
No bayonet fittings....
Any help would be appreciated..
Alan
