I am in the process of getting a back to back gauge produced for me by Model Railway Parts. I have been after one for a while, I am aware of what is on the market but they are not quite what I am after.
The gauge will be similar to the standard gauge one they offer at present http://www.modelrailwayparts.com/Product-Track-Gauge-Back-to-Back.html
The back to back will be 12.4mm.
At present I do not have a cost for the item, as with all things the more I order the cheaper it will be, so I am looking to see what the interest in such an item would be.
I have ordered 5 to start with but if more people are interested I can get a price on what an increased order would be.
If you are interested let me know.
I know several people have made excellent ones, but I do not have the skills or equipment to do so.
Kind regards
James Hockley
