I disagree with Studley a bit here.

1970's WMS machines are not highly sought after, mainly because WMS churned out the same game over and over in a different art package.. lack of drop targets in the 70's was a real stupid decision on WMS part.. hell.. everyone wanted them.. and still do!

BIG DEAL is a bit different for a WMS game.. look 2 sets of drops!
Game looks to be in good condition.
FACT - WMS games are waaaaay faster than GTB of the same era.. this game will fly.

Trust me... WMS games with drops are like hidden treasures that very few have discovered.

Read the IDPB comments... game is a player for a no frills pinball machine.
Put it this way... this game for play will be way better than any GTB HIGH HAND etc... yet if it was HH on sale for $1000.. collectors would be licking their lips.
WMS made faster machines... id say that this game would be a favourite if bought
