I bought these locks to put into a cabinet made in the 1800's. I had to modify the existing mortises to make them work, but I knew that in advance. I also fabricated striker plates. I was pleasantly surprised these locks were not Chinese, but made in England.
I ordered this lock based on the fit instructions on the website. The product was well-made, very precise, and most important it fit as described. I would order from Paxton again without hesitation.
