\"Coil<\/p>\n

Last weekend at the Electronics Flea Market<\/a> I picked up some very strange items, including this one, pictured above.\u00a0 It’s a tin can that looks very similar to an ordinary soup can, except that it has the following markings on it:<\/p>\n

R16-C-28604-15
\nCOIL
\nQTY.1<\/p>\n

NSC.OAKLAND JULY 1953
\nPRES METH. 2D<\/p><\/blockquote>\n

Thus far the only information I have learned from the markings are that NSC.OAKLAND stands for the former Oakland Naval Supply Center<\/a>, closed a decade ago in 1998.\u00a0 According to Wikipedia, NSC supplied components to the fleet in the Pacific during WWII.\u00a0 Beyond this I have not been able to find any information.\u00a0 Presumably this is a replacement part for some piece of obsolete military hardware.\u00a0 A “coil” is another name for an inductor<\/a>, a clue that this may be part of a radio system or other high frequency equipment.<\/p>\n

After staring at this mysterious object for almost forever (a week) I decided to open it.\u00a0 Realizing that the can could be full of cold war era hazardous chemicals, munitions, objects under high compression, or nasty sharp edges, I did this very carefully and documented the entire process of discovering the contents.<\/p>\n

First, the obvious – opening the can.\u00a0 Pretty straightforward.<\/p>\n

\"Coil<\/p>\n

What’s inside?<\/p>\n

\"Coil<\/p>\n

Weird.\u00a0 Lots of oiled green paper.\u00a0 Whatever is inside is packed very well, when the can is shaken nothing moves around.<\/p>\n

This is the clump of stuff to come out.<\/p>\n

\"Coil<\/p>\n

Packing material?\u00a0 The precursor to styrofoam peanuts?<\/p>\n

Below the packing material…<\/p>\n

\"Coil<\/p>\n

What’s this?\u00a0 Vintage dessicant<\/a>!!!<\/p>\n

The last object left in the can looks interesting.\u00a0 It’s wrapped in oiled green paper and sealed with tape.<\/p>\n

\"Coil<\/p>\n

Inside the paper we find this:<\/p>\n

\"Coil<\/p>\n

Not a huge surprise – it’s a coil (inductor).\u00a0 It has a knob or grabby thing on the top and a funny connector on the bottom.\u00a0 It looks brand new.<\/p>\n

Here are a few more pictures.<\/p>\n

\"Coil \"Coil \"Coil \"Coil<\/p>\n

The markings are “ARC” and “7270 239 KC”.\u00a0 ARC might be American Radio Corporation?\u00a0 239 might be 239 kHz (kilocycles)?\u00a0 Hard to say, google didn’t turn up anythign interesting.<\/p>\n

An impressive amount of stuff was packed into that can!<\/p>\n

\"Coil<\/p>\n

This solves the mystery of what’s in the can, but what is it for?\u00a0 Does anyone know?\u00a0 I’d love to find out – leave a comment or contact me directly<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
