They might have been once but there main business these days is sticking their logo on imported TSOs.

Much like Record, Marples, Britool and a host of others:(
I think you'll find it's a bit more complicated than that.

My 40 year old Britool spanners are probably ok, then. Phew.

Yup they will be fine :) I have a lovely big set from the early 80s that my Dad gave me.

<slight thread reheating ...>

Draper do a CF version of their 6" product which is way cheaper than the normal one:
https://www.drapertools.com/product/24816/150mm-or-6inch-Carbon-Fibre-Digital-Caliper-Gauge

I'd never heard of CF being used for jaws/parts before - there MUST be a drawback if they are so much cheaper. Surely??

The only carbon fibre in those calipers is the material used in the injection moulded nylon jaws.

Filler such as glass or carbon fibre is added (in the form of small beads or short lengths of chopped filament) to the plastic before moulding to change the material properties.  Usually for increased stiffness, but it is also slightly cheaper than pure nylon.
