This is an unusual item which equates to N gauge (1:148) ..… it could be described as a set of “overhead offices” in good used condition. The model appears to have attached wiring but I was unable to get/achieve any light on the matter. I have been informed by a learned ebay colleague that it is in fact a Vollmer Kit 1:160 which equates to N gauge and it’s a Gantry Signal Box, so I have adjusted the listing accordingly.
