I'll try to get the CD discussed above, TKS . I located a number of Leblanc's US patents, those of early date are Leon's, followed by Vito, about in the 70's. My earliest [jump keys etc] is US 1,926,489, followed [in #/date order] by 2.627,776, 2,832,250, 3,079,828 **, 3,136,199, 3,191,482, 3,237,504 . I have read [studied?] these, in partic. the **828, which I believe was L's answer to licensing negotiatons with Stubbins [of earlier date] on the improvement, re: OUR problem, with the "pinch"/mid-staff Bb. I'm sure there are more [and later] of note, may add them if anyone is still interested, Don
Thanx, Mark, Don
