Bob, I've got to make a couple of these, and these are the tallest single-aspect searchlight I've ever seen.http://www.rrsignals.net/Atsf/Albuquerque/2ndDistrict/EastPass/EastPass.jpghttp://www.rrsignals.net/Atsf/Albuquerque/2ndDistrict/WinslowYard/WinslowYard.jpgWhen you're looking at the kits, any way to see if the mast & ladder length can accommodate anything this tall? Or any way to modify (i.e solder ladders together, or have a longer piece of tubing would do it)?
What diameter mast are you planning? The sample looks larger than 3/64" that I've been using. The 3/64" is even a bit oversize, but a good compromise when needing to feed 9 magnet wires down the shaft for a triple headed signal.
Will the LED modules work with the old version PRR signal heads?

...available at Component Supply Company now, here: http://www.componentsupplycompany.com/hypodermictubing-size-chart.html ) and found some stainless steel 304 hypodermic thin-wall tubing that with a coat of paint, would be perfect. It has a .0355"/.036" outside diameter, with a .025"/.027" inside diameter, which makes the wall thickness around .005". With an opaque, thin coat of paint (.0015") that'd make the OD .037"/.0375"....6" being .0375" in 1:160th....
Already done Randy, look at the center sheet of ladders I posted here:https://www.therailwire.net/forum/index.php?topic=31944.75The electrical box base was done for these styles
Nice. I daresay that may be better than the 3/64 tubing by K&S that's available at hobbylinc and some other places. Somewhere or other the old guy at Sunrise found some thinwall brass of about the same dimensions. Curious if anyone knows of other sources.
I get my thin-wall brass tubing (and other shapes) from http://www.specialshapes.com/ . They are now a division of K&S, but they still carry a full range of excellent scratch-building supplies. The website is not the greatest - but they are easy to deal with over the phone.
