I've found a couple with the vibrato (365's) but usually an "R" Tail like mine:

I have seen the trapeze on many double bound 360's though.

This one is sweet! Although it is a 12 string 360.
So what's the deal? Were the 360's (unbound front) available from the start with only the "R" tailpiece,
unless you ordered a 365 with the Vibrato?
Thanks for any help.
