The Revell set is nice, they are well moulded, but... They are a bit on the big side. I managed to get a set for a non-extortionate amount when I was looking to populate a diorama and collected as many different ones from all the decent sources I could find. They come up big against all of the others and illustrate the issues of mixing HO, OO, 1/72 and 1/76. People are different shapes and sizes, but not that much. They would be great on their own though.
I think the one that puzzled me was the radio operator: really nice, but even in a Lancaster you’d hardly see him.
