I am looking for large Imperial eagle emblems and similar symbols, to add to 1/35 railway models which I will use as terrain and objectives. I know that Forgeworld sell a sheet of etched brass eagles, but they are a bit same-y for my needs (and expensive.)

Forgeworld Medium Etched Brass Eagles

I am building the train models and converting them a little with GW kits and leftover bits. However, some eagle symbols, a few centimetres in width, would really 'sell' them as Imperial equipment. I don't have the time or patience to cut them from thin plastic, so pre-made ones is what I am after. Any ideas? Polystyrene, resin or brass, they are all good.
