I don't think its that straightforward. Beretta SO series have a variety of different (at least 3 types) of sidelock with different pin counts. To the best of my knowledge ALL have intercepting safeties.

Purdey locks have (I think) a similar pin count, but NOT ALL have intercepting safeties. Some use a bolted sear instead.

I don't think intercepting safeties are of great importance. One of the few accidents I know of that happened to someone I know was on a gun with intercepting safeties that fell to the ground being passed between a loader and the gun shooting. Despite intercepting safeties, the gun fired due to the jolt. One parties was injured, fortunately not in a life threatening way.

I have guns with and without intercepting safeties and don't consider one safer than the other. ALL loaded guns can go off.

I do, however respect and understand your desire to know what is in your gun. I have taken photos of locks on some of mine to allow things to be looked at at a later date if needed so that I can refresh my memory.
