Hi James - 1/72 & 1/76 are pretty close, but a difference will be apparent if you place the models/figures of different scales close together, 1/76 being smaller. Example: a 1" tall figure in 1/72 would represent a person 72" tall (6'), a 1" tall figure in 1/76 would represent a person 76" tall (6'4"), so a 1/76 figure of a 6' person will be shorter than a 1/72 figure of a 6' person This, obviously, also applies to vehicles etc. I hope this is helpful. Also, I understand that the forthcoming 1/35 Cromwell tanks will be Airfix' own tooling. Im pairing 1:76 vehicles with 1:72 people so it should be fine
