Summary:prominent nose-stop & lathe-turned lower gate stop
Description & Commentary:

This steel carabiner has 3 interesting features:

a) prominent stop on the nose for the locking sleeve, which reduces jamming compared to something like the Stubai which has a nose-stopped sleeve, but stopping surface

b) a lower sleeve stop on the gate formed on a lathe, perhaps as part of the same operation which formed the locking threads

c) pins (not rivets) left proud of the gate surface.

The Foin brand is owned by Honeywell (home of Miller and Sperian). Lyon Equipment has a bit more about the Foin brand. I have asked Honeywell to confirm the part number, but they seem to be having trouble tracking down this particular model (steel, D, screwlock). I believe this is an older (unmarked) version of the Foin 4249. The technical notice linked on this page is from another retailer's website, but does have the 4249 model listed on the document.
