SB. I've no idea who you are, or how much experience you have in these matters. However, there is a small problem of copyright law. Doing what you propose could land you in court, with a lot of copyright fees to pay, plus a lot of legal expenses.

Also, there is the question of protocol to be considered. I know that Bulmer's reputation isn't too good in most quarters. Even so, if you're seen to be issuing non PD recordings, without so much as a by your leave from his estate, you might find that no-one else in the folk record industry is willing to work with you.

Having said that, if there's anyone out there who can re-issue the stuff legally and legitimately, I'll be only too glad to give them all the help I can - as I did with Rod Stradling when he reissued the Cecilia Costello disc.
