Bill: If the next generation is going to put the guns back in the field, I would recommend a complete tear down, clean and lube. No doubt the guns will probably shoot without that but when closing in on a century, the innards could use a day at the spa. The three pieces the guns break into - forearm, action and barrels are actually around 100 parts. There will be hardened oil, dirt, grit, rust etc that is not visible and that does interfere with smooth functioning. Make sure the gunsmith is familiar with Parkers. For interest, here are the parts in a Parker VH action. This one is ready for another century now and has already taken a few wild pheasants.
