O. K. H. Cartridges

Many of you may not be aware of the O'Neal, Keith and Hopkins, OKH  line of rifle cartridges. On my last visit to Mr. Keith, summer 1980 I believe. Had gone by his home in Salmon to see if I could acquire a  338/378 Keith Thompson cartridge. He was all out, but after finding out I collected cartridges, he went to the basement and came back up with these shells. Needless to say I was elated to have them, especially since they came from him and were loaded by him. Pictured are left to Right. 280 Dubiel, 285 OKH with the extension tube inside, 338 OKH Belted, 334 OKH, 400 Whelen, and 424 OKH. Would be glad to hear from any of you Keith fans on these
