Measure the distance from the edge of the door to the centre of the hole for
the outside key. These days there are two standard widths, 40mm and 60mm. I
fitted a PBS2 to my mother's back door recently. The lock it replaced (which
was marked in imperial) had been there at least since I can remember, which
would have been about 1978. The 40mm fitted perfectly, so I suspect these
have been standard sizes for decades.

Great - looks like it's 60mm.
