Oh Dear .... Sorry, Graham, but to call the Frog Marauder "accurate" is to talk through one's intercooler. Basically, and to a first approximation, Frog in those days differed from Airfix in that Airfix worked to the "plans" in their copy of "Aircraft of the Fighting Powers" and Frog used those in "Model Aircraft."
As all these drawings were compiled under wartime conditions they were both "by guess and by eye" and the kits made from them looked ok but wouldn't stand measuring. In particular, Frog's B-26 has flying surfaces which are about half-way between the early and late sizes, and a fuselage which is too long and fat. Lots of detail is wrong or missing and all the wheels are noticeably too small.
About a year ago I finally finished my second of these kits - long story - as a B-26-nothin' (as it's easier to cut down than build up.) It's a nice kit by 1958 standards, and fits a treat, and all that: but for a good quick '26 my money's firmly on Airfix and a bit of rescribing .
