Andy,
Indeed great news. Just to inform everybody, I wrote to Acme with all my photographic evidence on this type (approximately 30 detailed shots of Bc and BR carriages), but I received no reply. I also pointed out the biggest visual difference between the Greek Gosa with the JZ one, which is the vent grille at one side of the carriage.
But modelling is how much one is prepared to compromise.
christo.
