It would be interesting to see, but economics stand against a ready-to-run model of 461. Only two such locomotives were built for the DSER, so there would be limited appeal in that regard. A brass kit would certainly be a possibility, though... as far as I know, no other DSER locos have been produced commercially, and the two moguls got to stretch their legs beyond their old stamping ground under GSR/CIÉ, giving more modellers an excuse to run one.
