Thank you very much Geezer. That's interesting.
I especially like the Sharp Miscellaneous page.
Will do some reading on Howa.
A few months ago a Dutch collector offered me his Taiyo Juki Deluxe.
I got the impression that it's very well designed and full of cool features, such as a power adjustment wheel and some Japanese artwork on the receiver.
I left it but who knows one day. Tom Gaylord wrote an article about the gun: https://www.pyramydair.com/blog/2009/09/taiyo-juki/
