As far as the time frame of the big dual cattle (early to maybe mid 90s)-Everything was big. The biggest cow Ive ever seen,( including other breeds and 1991-in Ireland)-was Deertrail lasting Impression-She was nearly 6 feet tall and guesstimates had her at 2800 pounds I didnt think about Waukaru Patent-Hes probably 7 plus maybe pushing an 8 :certainly a big bull by what I see for their sires.Deertrail T bone was very tall,along with Sagebrush who went to Backenhus-T Bone would still be back in the Della Daiseys,Final Solution etc as a great grandfather-He was a mid 90s deal.-Ive seen tons of Byland cattle and started with them: as well as offshoots-They are bred to get there real fast then level out-like Angus.The last bull I saw that tall at Byland was RPS Hutton in 1991 Most of the available Canadian bulls I see are massive-but dont look that tall-at least in the pictures Im sure: JIT, Ockotocks ,Muri and others on here would be a good sounding boards. The thread says recent-I took it to mean 8-9 plus frame bulls-in everyday use: today.Not clear what clone you are referring to O0
