The photograph below have been posted on the History of Georland blog but I thought I would put them here for anyone who hasn't found their way over there yet.
It has emerged that most of the figures are demi rondes of around 30mm size for foot figures. Many were Franco Prussian War figures bought cheaply in around 1873 and repainted or otherwise converted. There are some flats in the collection as well - these are thought to be a later addition.
Any definite identification of manufacturers and subjects would be very welcome.
