Hector, an excellent article on one of my favorites! One doesn't see much info on tuning these guns, so very interesting. I bookmarked it and took a lot of notes!If you allow this annoying trivia nerd to make one minor correction - the LGV in your first photos is not an Olympia stock, but what Walther collectors call the UIT stock.Walther's first "Olympiaschaft" guns were rimfire match rifles made in the 1930's. The name honored the 1936 Berlin Olympic Games, but "Olympia" became a sort of generic term for that attractive, rounded, full-bodied style of woodwork. (The Diana 60 in your photo is a classic of traditional Olympia styling.) The LGV Olympia stock is extremely comfortable, and to my eye a really beautiful update of the pre-war style, with cleaned-up lines, less raked grip, and brilliant handling. The squared-up UIT stock mirrored Walther's rimfire match rifles of the late 1960's (the UIT was the regulatory body preceding today's ISSF). This stock was used on late LGV's, and early LGV Specials, whose main mechanical difference was the counter-wound double springs.Top to bottom in this shot is an LG 55 T, LGV Olympia, and early LGV Special with UIT stock.
