This is a Georgian gentleman’s treen library & gallery magnifying glass with a turned handle and a lovely reeded circular frame. There are brass fixing attachments where the handle attaches to the frame. This type of magnifying glass was used to inspect paintings amongst other things and is often referred to as a viewing glass. It has at some stage had the glass replaced, many examples do and is in full working order.
It measures 33cm l x 16cm w x 2cm d.
