I've only seen one. Ollie sent it to me years ago , well actually it was a rifle and a half and it was a swine. It had the most woodwormy stock Ive ever seen and the stock screws screamed coming out.
What I did notice it that one of the actions had wider trigger bits than normal. I cold blued the action after usiing fine sandpaper on it and it was not a bad finish. I think the tube was a little loose and I told Olle to find a washer to take up the play when I sent it back to him . It worked ok but i'm not sure whether I had to use flat heads.
As far as I know Ollie still has the gun?
Mr Gilkes should be able to tell you more.
