More than a year ago there was a discussion of a bullpup prototype by one Marco Rigido:

I plainly wrote that I did not like signore Rigido's invention. I looked up his website then. Well, I was not awed by the guns shown there, rather amused. I saw a .500 jeffery rifle with a boxy, military style single-row magazine, cheap-looking "factory" style checkering panels and a curved bolt handle in a straight cutout. then an "engraving carrier" of a backlock hammer shotgun, underbolted only with a squarish belly.
Mehulkamdar then challenged as not being a gunsmith myself and asked me to show a gun made by me before criticizing the works of a "great master" who gets awful lots of money for his work. I forgot about that challenge until I browsed through old threads today.
I was never trained as a gunsmith except by the "school of cut and try" and some obsevations of the work by others. In fact, I am a (now retired) forester who does some hobby gunsmithing for my own use only.
As Mehulkamdar asked, here are a half dozen rifles from my collection. Made over 30 years, the last one was made about 5 years ago. All were designed, stocked, sighted, finished and well used by your's truly.

From top to bottom:
7x57 on a 1912 vintage Mauser Oberndorf commercial intermediate length action.
9.3x62, Mauser 1930s commercial standard action.
.416 Rigby on a ZKK 602 action, barrel rebored in Suhl from .375, made 1991.
9x57 on a WW1 military action, barrel rebored in the 1930s, done 1978.
10.75x63, barrel by Kalezki, Vienna 1906, Mauser Intermediate length action.
.45-70 on a (unsplit) Greener Martini police action, barrel blank from Numrich.

I never filed any patents of my own, as anything worthwhile in gun design was already patented more than a hundred years ago and is now in the public domain. You just have to do a bit of research.
