I have not built the Revell kit myself. From all reports it goes togther well.
As for decals, have you considered aftermarket decals for the No 6 aircraft?
CAM Decals do a sheet in 1/48 http://www.aircraftresourcecenter.com/Rev2/1901-2000/rev1934-cam-p48018/00.shtm
I am not sure of the availability, you will need to do some trawling around the net.
