I have a Dapol 8750 with which I am very satisfied. Running is excellent on DC. I have changed the (rather short) whistle & shield with one from Warren Shephard, and added spare lamp irons on the running plate. If the smoke box plate is not required I would think it easy enough to remove and fill the resulting hole in the smoke box door. There are plenty of photos of panniers in GW livery with a smoke box door plate ( early BR), just depends on your chosen period. The Minerva 8750 looks very nice but has incorrect tank fillers.
