According to Walter's Airgun Book (the 84 and 87 editions) there was the 851 (introduced 1983, discontinued by 1987) which was a single stroke pneumatic with a one-piece wooden stock, this was though of "sporting" style although it did form the basis for the model 953 Match Target.
In 1986 the 920 and 970 were introduced, in .22" and .177" respectively, which were multi-stroke pneumatics with separate butt and fore-end (and with a separate pump lever in the fore-end) and fed from a 5-shot magazine. Quite how long they remained in production, though, I don't know.
He doesn't illustrate either of these models but of the 920, in comparison to the synthetic stocked 922, he does make the comment that "it has lost the subtle elegance of the original plastic version" - presumably the wooden stock didn't have the chequering, cheekpiece or comb of the synthetic stock.
