SteelerFan,
I'm NO expert but I've heard stories while attending
tournaments that Tudor would,on occassion,mix different
side & end rails when they were running low/out of certain ones.
I'm sure I've seen some missed-matched boards over
the years but couldn't describe any of them.( old age)...LOL
As for that switch.That's more than likely a "home-job".
This I do know,on the original switches,the wires had to
be soldered.So if you or your dad or neighbor didn't
know how to solder you had a broken-switch.I see why
this cat used a wall-switch. ( screw-terminals) That was the
best thing they ever did with this particular switch,put
screw terminals in them so "most" folks could work with them.
Even a kid could fix it,usually.
I'm hoping Ray Fanara or Mike Pratt see your post.They are
well versed in EF boards and can answer your questions.

SEMPER FI,
Chris Stacey
