slider door handle set in bronze

home was built in 2005. the lock swich broke. it looks like a tear drop. the locking pin is about 1/4 inch wide and slides into the lock itself. not sure what other info I can give you. i found one in florida but it is black and I need it in bronze. it is made by Amersbury Truth. The part number on the invoice is BNT1.1 but I think it is unique to the store and not the actual part number
