I can supply basically 2 types of Gauge for 0MF in turned brass. A normal plain track one, with two grooves and one for setting the checkrails.
The reasons I don’t normally supply a combined gauge are that, including the checkrail part with the plain track can lead to problems. The gauge would be difficult to use in the vicinity of the point blades and could lead to a gauging problem if gauge widening is needed at the checkrail area.
Price is £8.00 per pair of plain track gauges and £9.00 for the checkrail gauge UK Post paid, Overseas at extra cost.
