Forget the recruiter pipeline unless he can find a recruiter (also an older person) who will take the challenge. He might be able to network with older coders in order to find companies that value older workers. Look for local tech greyhairs socially or online and reach out to them. Pitch as a no-hassle guy who is mature, flexible and willing to pick up any stuff that others don't want to do as temp, perm or part-time. Above all, find many ways to talk to many people about their work and his interest in current stuff. Try not to go CV, then F2F - that's a losing game for older workers. Find any way to do F2F or chat first and CV if there's interest as a formality after.
