Apart from the turnout/trackwork side of things, Stephen Freeman also builds signals to order. He has recently introduced a 'no frills version' of an LMS/BR UQ tubular signal, GWR(WR) square post LQ signal and a GWR(WR) tubular signal (see photo below). These are are all metal models. Further versions will follow in due course and there are more details on my website. The signals will be made to order only, at least initially and the price will be £12.00 for the 4mm scale versions and £21.00 for the 7mm scale ones - inclusive of carriage. The signals will be available in either home or distant versions.
