Hi, my house built in 1948 has 7 Yale 2-lever internal mortice locks as follows:
backset 2 1/8"
case width 3"
case height 3 3/4"
forend length 5 1/4"
forend width 7/8"
all are now wearing out. Inside the escutcheons it says "Yale no. 300" and "Made in England".
I can't find mortice locks with these measurements anywhere. Most locks seem to have a backset of 2 1/2". If anyone can advise re where I can get them, I'd be very grateful.
thanks
Peter.
