I'm not entirely sure what year it is to be honest, haven't done my research just yet, my guess is late 80s/early 90s going by the colour and stickers. It would appear the 140 wasn't offered in the north american market from the brief read up I have done. This one was originally purchased in England going by the dealer stickers and made it's way over to Ireland ten years ago or more from what the previous owner told me. Although his credibility is looking shady at the minute!
Yeah I was expecting something in the 120psi region but the (borrowed) compression tester I'm using is showing figures in the mid forties, with less than 5psi variance between cylinders. This seems unlikely to me though given that it starts and runs reasonably well, it is suffering from a slight miss-fire but I'm inclined to think that's an ignition issue having noticed the (my terminology fails me here) arm which advances and retards the spark under the flywheel is sticking, I would guess due to the engine being unused for some time.
