I bought the correct decals from Graham, the Regalia Officer BSAOC and the are the stick on type which are much better than the water slide. However you only get one chance so make sure its in the correct position before it touches the tank as you can't reposition them. The benefit is, they look great and as its only the gold line that is actually stuck on, there is no oblong clear patch to crinkle up when lacquering over the top.
They are ref 005 and are £2.50 a pair (+ £1 postage) contact regalia@bsaownersclub.co.uk
