Hi Ed,

Perhaps I might suggest you throw up some pictures, that would help with input to your needs.
It also allows us all to share in your Joy with a Neat title.

The evening crowd, after work, should jump in with some help.

Are you trying to remove the backglass or the playfield glass? The playfield glass may be held in by the wooden lock down bar on the front of the cabinet which is usually held in place by threaded rod posts and wing nuts. If you remove the coin door you might see the rod and/or nuts hanging down from the top of the coin door frame.

The photo on ipdb at http://ipdb.org/showpic.pl?id=2638&picno=63038 shows a row of light sockets on the left side of the backglass (looking from the back). These may illuminate the diver descending as you progress through the game. The diver images may be just silhouettes, or holes in in the masking layer of the backglass that just let light shine through the other artwork.

I suppose that would be considered pre- Korean war.

I have a '47 Exhibit. There are two screws at the upper left and right of the head that hold a small piece of trim on. That lifts off, then the backglass can be removed vertically. Make sure that the insert board (the one that holds the lamps/transformer) is pulled back a hair (screws on the sides of the head), and use a small piece of painter's tape on the front of the glass to help you lift and pull towards yourself (the routed channel for the glass is larger than the depth of the glass).

Get your other hand underneath when you've lifted it enough and you can maintain even pressure forward and up all the way out. This should help you prevent scratches and other blemishes when you remove.

But you still have to be extremely careful. Unfortunately, modular backglass removal wasn't around for another couple of years (except in some Bally games).

Congrats on the Treasure Chest! I've had that one on my wishlist for a while now.
