Well, if Revell redesigned the entire mold-set, then maybe it is, but I highly doubt that happened.... The picture looks exactly like the old Monogram Patton, which was 1/32.... It's pretty obvious when set alongside the Tamiya M48... I know the catalog says 1/35th as well, but I doubt it..

But don't let that hang you up..And 1/35th accessories look fine on it, as long as you don't mix after-market/parts box accessories with the kit accessories, or mix the included figures with any other 1/35th figures... No need to be pizzed...
It's still a fun build...
It's the same way with all the old Monogram armor kits, like the half-tracks, M-4 Sherman, T-34 Calliope, M-3 Lee, Grant, Panzers all, Weasel, Jeep, etc.... They were 1/32 as well.. But you won't notice it unless you put them right alonside other manufacturer's kits of the same subject in 1/35th..
Monogram was one of the kit manufacturers that want the standardized scale for armor to match the 1/32 aircraft market, but it never happened... The Japanese manufacturers, like Tamiya, didn't follow suit, and Monogram got buried by 1/35th...
