Old Laser question

I'm an experienced recreational sailor,, looking to sail local lakes in Central Oregon. I've located an old laser, made in 1975. Boat has been garaged for over 20 years and appears to be in good shape, including the mast well. A 3.2 sail is included with the boat. Can it still be sailed, and are necessary parts available? Boat serial number is 29228

I'd appreciate any and all advice.
