Indian Locks

Indian Locks Had a call recently to open 3 internal knobset locks all with the same key for an Indian man who had been on holiday and come back to find he had closed the doors and left the keys inside one of them but not sure which one. Opened the first door nothing. Opened the 2nd Bingo. So all was good with that. But on leaving I happened to look at the locks on the main front door and was quite amazed to see the lock he had which he said he had purchased in India, never seen one like this before. I would never have thought of looking to India for locks. Wouldn't mind one of these on my door.
