Howdy Carol and all,

The round disk below the "arm" is actually a very thin (beryllium copper?) disk which vibrates due to an electromagnet in the coil box.? On this disk is a contact which makes the connection to fire the high voltage coil.? I do not think you have any other coil parts in your collection that I see.? Model t spark coils are somewhat unique in that they do not spark once but make a continuous shower of sparks as long as they are energized.? If anyone is interested and finds themselves in Northern California, I would be happy to demonstrate, just let me know.? 

Best,

Stathi

Well, I tried to send this to your AOL email Stathi...but, it bounced
back on me.  Looks like our IT guys havent fixed All the problems yet.
So...everyone gets it.  Sorry.

Ha!  Some 30 min. before I saw your email...my co-worker told me what
this item was!  I had set it aside (since last wk)...leaving the
Unknowns until today/this wk...and while I was examining it...he walked
by and said "I know what that is"...but then he couldn't Remember the
name of the box...until a while later.  He's an old car buff.

So...let me ask you (since you have tinkered with one of these recently)
about the disk hidden from view by the 'main arm' of the contact.  Is
this just a washer? Or...is it a disk with a plugged hole?  Why I am
asking is...would it be the #8 item shown in my group shot...right above
#9 that you knew??  This disk is marked SAMPSON BRASS PLUGS.  I havent
been able to find any info online even with this full name, AND the
patent dates - PAT APR 19 93 SEP 6 99  (darn Google keeps changing
Sampson to Samson!).

:o(

THANKS for the link.  I had come to my desk/PC to check online for how
the contact was affixed to the coil box...when I saw your email.  What
weird timing.  :o)
