[sdiy] Mysterio Electro

[Senso]

Hi all,

In my never-ending hunt for obsolete parts, 
there's of course always some by-catch, like with 
fishing for shrimp. Sometimes an old boot, 
sometimes a real gem.
Out of a surprise box that I recently received, 
came things that I've never seen before and 
therefore made me curious.

No.1 is a military surplus board with - for me at least - mysterious function.
It's a small PCB with eight copper spools, all 
connected to 2-position rotary switch.
to be seen here: http://www.vintageplanet.nl/pics/parts/PCB.jpg
What the ... is this and are those spools useful 
for anything in this day and age?

No. 2 is a number of 8-pin relays of obvious 
sturdy (somewhat archaic) quality, visible here:

It's hard to establish it's exact part number, 
with all these markings on the side:

RELAIS  1470‡
SM 26 E3 S6-41
1860   0548 159

Who can satisfy my curiosity?

Thanks,
Senso
