Unidentified binding stamp bearing three heathcocks (17th cent.)

This armorial binding stamp has been attributed to several owners, but remains unidentified. It seems to have belonged to a medical man from the mid-17th century, judging by the volumes that bear it, and the two volumes that do so at St John's are copies of the medical works of Sebastiano Paparella (1582) and Antonio Fumanelli (1557). Both books were bought with money left by John Collins, and both have the arms stamped in blind, although one bears what appears to be the remains of silver leaf.
