I just recently learned that you can still buy the MK1 style HW97 brand new, minus the 25mm internals of course. An outfit in Germany still stocks them, current production. And in a combination of about any current Weihrauch stock/action combo.
Haven't had a 97k in a long time, I need to pick one up again here soon. Got a few 77Ks, but no 97K.
Helluva nice collection you got there Mike!
