Getting Narrow M... ähh... Gauged

If you need brass detail parts, English's Model Railroad Supply is the place to get them, as they're the ones that are making the Cal-Scale detail parts.
Whenever I go there (not for the last couple of years, though, due to the pandemic) I spend at least a couple of hours browsing through racks and racks of brass detail parts...if you need an air pump, there's probably 5 or 6 variants available, and it's similar for most detail items, such as check valves, water pumps, handrail stanchions, etc., etc.

Here's a LINK to at least some of the parts that are available.
