A local camera repair technician, if there are any around still, would be able to clean, lube and test the lens accuracy. That is if you intend to be serious about large format shooting. If this is just exerimentation to get exposed to large format photography, do some tests on your own, doing as Randy suggested.
Before taking the lens to the technician, do a couple test shots to make sure you don't have light leaks, or to find and "fix" the light leaks.

Set aperture to f8.3 or whatever fraction the shutter speed is off by. But you are going to need to test to even know what the shutter is actually producing speed wise. Its probably not very accurate any more.

Hi,
I recently bought an old large format field camera that came with a lens which is so old it has shutter speeds that don't correspond with my light meter; it has 5th, 10th, 25th, 50th, 100th, 200th, instead of the normal shutter speeds (8th, 15th, 30th, 60th etc.)
So my problem is trying to work out what the correct exposure should be...working from my meter. I'm shooting colour negative, so I'm guessing it can take a bit of latitude either way, but can't quite work out if I should go with an exposure that is slightly over, or slightly under what the meter says. For example, if my meter reading is F8/125th, should I shoot at F8/100th, or F8/200th?
Any input appreciated.
Cheers,
Jonathan.
