Looks like the body is refinished, missing original pickguard screws, missing original tremolo arm and spring. As well as the original knobs. I suspect the pickguard is an original Mosrite pickguard, but perhaps not original to this guitar, I'm not sure.
The guitar came with the original tuners, but they feel quite brittle, so I swapped them with exact replacements, I put the tuners away to preserve them. I purchased a new tremolo arm and pair of springs (Light and heavy) from Bob Shade (Thanks Bob). When I acquired the guitar some of the leads from the pickups were either soldered in the wrong place, or not soldered on at all. Whoever refinished this guitar must not have known how to solder the pickups back in. Wasn't a hard thing to fix. The guitar was also missing a ground from the bridge. I did a reading of the pickups residence.
Bridge Pickup: 10.6K
Neck Pickup: 8.19K
The pots, jack, and toggle switch are all original and work fine. The pots are a little scratchy but thats all.
Here is the headstock right out of the box when it arrived. Still dirty, original tuners (I replaced those later on to preserve them). 0 Fret looks a little worn.

The neck was not dated, unfortunately.

The neck pocket was painted over, so also no date.

The body with the pickguard (with original wiring ((crap solder job on the pickups)) ) as well as the pickups and tremolo removed. (Note only 2 of the 4 holes drilled for the neck pickup ring. Never seen that before.

Another shot of the body, pickups moved aside, can also see just how filthy this guitar was.

Here are the undersides of the pickups.

Got the body cleaned up nicely. Added a ground wire for the bridge (Yellow wire).

Here is a shot of the fixed wiring. My wiring isnt great, I know. I was trying very hard not to undo any of the original solder points. (Thanks to Forum member Volts101 for sending me photos of the inside of his 1966 Carved Ventures II).

Heres a shot comparing the old tuners (left) and the new replacements (Right)

Here is everything put together, with the new tremolo arm. (Thanks again Bob Shade).

Here are a few shots of the guitar with strings on it.




Overall I'm very happy with how this guitar cleaned up and how it plays.
Special thanks to forum member Volts101 and Bob Shade of Hallmark Guitars for the help!
Glad to be a Mosrite owner.
