Found this mentioned somewhere online but couldn't access more.
It relates to the whole of Great Britain, but having considered this I think it may all be kept at Kew!
'Registers kept by the Board of Stamps of the moneys received in payment of the duty on apprentices' indentures under the statute of Anne c5 and subsequent acts.
In addition to the sums received the registers record the names, addresses and trades of the masters, the names of the apprentices and the dates of the articles. Until the year 1752 the names of the apprentices' parents are given, but after that year very rare.'
