It is simply a matter of quality of work. Those who do not appreciate it, don't need it. I guess you fall into that category, which is fine. A two pin bridle is a feature of a cheaply made lock in general. Even three pins is pretty low grade.
I don't know why these discussions always seem to become so puffed chest 'my dad is better than your dad' in nature.
Yes, we know that cheap, simple, large limbed mechanisms still fire the gun and work for years and there is nothing wrong with them.
However, critical examination of all the locks posted will show very different levels of quality of work and finesse.
If 2holer appreciates rugged, then the Anson & Deeley should be his ideal but you can examine different A&D locks and see more quality and finesse in one (say, a best grade Westley) than another (say a cheap grade Midland Gun Co) - see, I chose two English examples so as not to upset anyone.
Brittany Man is not having ago at your gun, Just pointing out that the quality is what it is and that he can see it, while you cannot. The point of the forum is educational in part, here is a good opportunity.
