It was listed by Jason Clarke Antiques. Sold pieces stay on Sellingantiques as a record of what has passed through, and the next one is rarely far away.
Jason Clarke Antiques has dated this Antique Brass Magnifying Glass to the 1850s.

A very generous size of its type with an unusually pleasant choice of handle wood, some scratches to the lens exit requisite with age but it does not affect its function.
An imposing magnifier which would have been used in either a library or gallery setting to allow closer visual inspection.
Circa 1840
