A fine example of a Birmingham made box lock.The engraving looks to be in the style of Henry Morris,who also had a shop on St;Marys Row,along with W.W.Greener and at one time William Ford.
The picture of the forge building is facinating,I have some pictures of this same area prior to its demolition it was a facinating area for a researcher to visit.
My own search of records, confirms Lapogus,s findings.
