Hi all. Just purchased 2 chubby padlocks and 1 chubb, door mortise lock ,which I believe to be of the night security lock type...I will post pics when the locks arrive and am feeling really excited ..I'm especially interested in the mortise lock because I believe it could be the detector type...will post some pics when the locks arrive,and I daresay will need some technical assistance.I am a newbie in the world of locks but Mr Chubb and sons have captured my imagination.I look forward to further communications
