Longwalker I agree with this description.In Canada the conventional accepted naming of Brno models is Model 21 - longer barrel rifle and model 22 - short barrel carbine. Either may be encountered with half stock (H) or full stock (F) I presently own a model 21H 8x57s and a model 22F 7x57. I have seen factory original 21F and 22H rifles as well but they are far less common.
I think most BRNO/CZ stocks are good as for some reason they seem to shoulder very well and keep the rifle from recoiling much, regardless of caliber. But on the other hand, I like the straight classic ZKK 600 stocks even better, yet not as much as the 21/22 models.while lacking a bit of finesse, to my taste the newer straightest classic 550 stocks are a better design than any brno ever made.
