A History of MGS in 50 Objects" aims to showcase some of the remarkable objects that belong to the Manchester Grammar School which is celebrating its 500 year history.
An "object" is being added each week. They're up to item 9 which is the Admission Register.
It's not yet online. You might try writing for a lookup, except for the years 1837-40, 1852–62 and 1879–88 which are missing.
Thanks to Hugh Reekie, a proud alumnus, for the tip.
