VMCC library is free if you visit (I believe still the case even for non-members).
It's well worth a trip anyway.......
From their website it's £5 per hour, max £25 a day, or £37 to join the club for free access.
That's not too unreasonable and probably worth the trip as you say.
I've searched the National Library of Scotland's database but can't find anything.
Thanks for the pointers
