This bookplate at eBay caught my because the Arms of Harries have been noted here before in an earlier post about Hatchments in Movies/Films. This bookplate’s blazon is:
Arms: Quarterly 1st & 4th Barry of eight ermine and Azure three annulets Or (for Harries) 2nd & 3rd Azure a fess between three falcons close Argent beaked and legged Or (for Philips).
Crest: A hawk Argent beaked and belled Or preying on a pheasant of the first.
