I've also included a pic of the treble side showing the holes for bolting together the bouts (I think). They are the same on the bass side and are the depth of the wings; they don't go through the neck-through section.
The serial number dates it to 1958 which raises the possibility this was one of the last Tulip 400's to be produced. Information I've been able to gather indicates the body shape was changed in '58 or early '59.
I love the weight and with light gauge 9s it plays beautifully over the entire fretboard. I use it every day in the shop. I find the single pickup a bit limiting for gigs, though I like to take it out to local jams. It's especially gratifying to see the looks on the faces of other players when they're told they're holding a 60 year old Ric.
