This is a I-would-sure-like-to-know topic. You are probably going to have to be a real old-timer to answer this.
In perusing 1949 Model Railroaders I encountered a company called Midlin Models based in a place called Scotch Plains, New Jersey. They manufactured a line of self-gauging roadbed which required a specially drawn rail that had a web(?) hanging below the track; this web fit into a milled groove in their roadbed. Early in the year their advertisement covered a half-page on the inside covers; this is an expensive advertising location. Later in the year it began to slip farther inside and by December it was restricted to a half-page single column back on page 70 or so; this indicates the company was in a measure of economic distress. My back-issues end at 1949 and do not resume until 1953; by that date the company appears to have completely disappeared. In looking at the ads the concept had some merit however this Midlin rail would have been unusable in any other situation than with their roadbed and that probably spelled the company’s doom.
I heard reference to this company in the club that I joined in the mid-60s - "We’re going to tear out that old Midlin track’. - until I encountered this advertising I thought that it was Midland track. The club was installing Tru-Scale self-gauging roadbed for all new construction; I have no idea when - or why - this club had made a decision many years before to use this Midlin rail and roadbed.
As I said at the head of this topic I am just curious about this Midlin Models Company if anyone can provide me some information.
Grateful!!!
