Bisset vintage AutoMatic Dart Scorer Board. Made in England. HARD TO FIND!

Description

Here is a mechanical Bisset Automatic Dart Scorer, made in England.
This darts game scoring board is rather hard to find outside of the UK and perhaps Canada.
Its made of steel and features six scoring dials. The dials basically function as a subtraction "calculator."
The score board is in generally good used condition.  All parts are present, including the original four hanging tabs and all screws.
All of the dials move easily counter clockwise, and clockwise when it is the only dial moving. The top row works as expected even when all three dials are moving.  The bottom row works as expected if two dials move, but doesn't move easily for all three at the same time. No attempt has been made to clean or refurbish this, other than a wipe with a cloth to get the dust off.
The 4 original hanging tabs on the backside are bolted to each of the four rear side corners - two on the top and two on the bottom.
The item measures about 17" x 17 3/4 inches x 3/4 inch.  It's heavy, which is why shipping is expensive.  If you live near enough in Northern California you can pick it up.
