Help with shield transfers.

[Rook]

Does anyone know if the Warlord Roman shield transfers will fit on Wargames Foundry shields? Just traded a load of scifi figs for a darkage army and as a 'deal sweetener' the previous owner threw in a carrier of "odds and sods" from his Roman collection which turned out to be 6 units of legionaries and a unit of auxilliaries. Mainly Foundry with a few I cant identify. Hello new Roman army!
Now all I have to do is find an idiots guide to Roman armies and away we go!
