A friend has a Kirby model 510, early 1950's, it runs, has cloth bag, burgundy handle. any ideas as to what its worth, should he spend money to update
thanks

For todays use it would probably have to be updated to accept disposable paper bags. That model came with a cloth shake out bag. As to worth, like everything, whatever somebodies willing to pay for it. You can find them for $5 literally or a hundred.
