I am trying to confirm if the "Grand Slam" Lancaster had roundels under the wings. I am also trying to confirm the size of the fuselage roundel. The Tamiya 1/48 Dambuster/Grand Slam Lancaster kit seems to have odd sized roundels, something like 53" or 54" (scale size) which doesn't seem to make any sense, I could believe 56" but my reference states 60".
Incidently the upper wing "B" type roundels in the kit are also much too small and should be 102". If you have any information it would be very much appreciated, thanks in advance
