Gary Stephenson wrotethis is an interesting one, I mainly see this lock as Chubb manufactured, but have seen some CM stamped……….Could this originally have been a Milners pattern lock adopted by CM and later Chubb?
Reckon so Gary as I think they did that for some of the safes and strongroom stuff.
Its worth a look on the Chubb archives site as from memory theres mention of cross branding regards the SRD products and grille gates etc.
It’s not always easy to find specifics though as from memory lots of it aren’t under history like the section covering the CM takeover etc, some of the best stuff is hidden away in the personal memoirs, and there’s pages of them!
It’s all worth a look if you haven’t already though.
Even the story behind the introduction of the plastic isolator parts and plastic SRD hinge parts are covered, who was responsible for them and the failures and hassle that ensued!
