This is very similar to one of your locks. This is a Amesbury door lock, patent # 6.264.252 and 5.820.170. It's a dual latch and the holes are 12" from center to center. The assembly is one inch wide. It has APR 09 inscribed on one side. I am not able to find it on your website. Please advise. Your help will be very appreciated.
