Since HW 55's have kinda floated to the top, here's a few. Weihrauch offered several different stock designs over the years, each (IMHO) excellently designed for one specialty or another.
HW 55 S (or SM). Plain beech stock, profile shape much like the M, but in tough beech, and a bit more rounded sans cheekpiece. Great all-round design suitable for range and field alike. This one from Robert Law's "Air Rifle Headquarters" days was supplied with a custom Williams sight.
View attachment 320032 HW 55 M (or MM). The classic Bayern match stock, perhaps the best-known variant and really lovely IMHO. Later ones have an accessory rail which can be a ton of fun to play with.
View attachment 320040 HW 55 T. Tyrolean cheekpiece. Several other makers offered Tyro stocks back in the day, but to my eye Weihrauch's is the most graceful. This fairly early one has a finger-groove fore end, barrel sleeve, old-style HW diopter, and double-threaded front sight.
View attachment 320028 HW 55 CM. A more focused 10-meter stock incorporating the deeper, more angular stock shape seen on many 1970's rifles, and an accessory rail. Actually a lighter, more pleasant-handling gun than it may look; this tuned one with an Anschutz sight may be my very favorite 55.
View attachment 320030 HWB Champ. Junior model from near the end of 55 production. A most interesting little rifle with a VERY short pull dimension, shortened barrel with weight sleeve, and adjustable-position trigger blade.
