Mortice locks

[Robotstar5]

What size are you looking for?

I found I have a number of "saved" locks if you are ok with secondhand and originality is more important than security

Edit: Just noticed your measurements, will have a look at the ones I have

I found a plan of the lock with dimensions.

Your original post says 70mm backset. The one in the link is 44mm backset.

I suspect that you may be using the terminology incorrectly.

In order successfully to find what you want, it will be important to use the words in the same way as everyone else who sells the item and measure the same dimensions as them.

You're right, I had the terminology wrong I had mixed up case depth and backset.

Your original lock is a Chubb, any Chubb dealer will be able to get you one. As suggested a proper locksmith should be able to sort you out.
