[ARC5] Wire

[J. Forster]

The WW II vintage cables I've seen are:

Aluminum flex conduit sleeved w/ wire braid and w/ loose wires inside.
That stuff is pretty much unobtanium, AFAIK, and the connector adapters
are scarce too.

Rubber covered multiconductor "control" cable. The problem is, you need a
wide variety (2, 3, 4, 5, 6, 7 conductors, at least). Getting such an
assortment, especially in #20 or #22 is costly. It is only authentic for
some systems, like the ASB-5.

Individual wires, either laced and held together w/ Adel clamps, or
sleeved in amber (clear 50 years ago?) vinyl tubing or sleeved in fabric
(the RCAF liked this in bright red!). I kinda prefer this option because
it easily allows a mix of wire sizes (#16/#18 for power; #22 for
everything else). This goes well w/ the clampless ARC-5 connectors.

A compromise is to use individualo wires in Expando tubing (black or
white). While certainly not original, it does look good, IMO.

I'm not a fan of ZipperTubing, BTW, although that is correct for 60s and
later mil stuff, especially GSE.

FWIW,
