The issue with Webley 700s ahooting loose is often attributed to the hingepin. It is not so in my experience. It is more often because the hook is quite delicate and this is generally where the wear occurs.
The other issue with the Webley 700 is the two retaining pins (screws) on eirher side of the action that hold the cocking levers. They are threaded into a thin section of action wall and often strip. The solution is to tap-in a holding pin from underneath the bar - can be done invisibly and costs around £60.
I just bought a webley built Army & Navy almost identical to Rocketman's Woodward - dated it to between 1892 - 1896. In the process of fixing it up - it has been neglected but was a quality gun in its time - very fine engraving and beautiful wood. Also has the screw-grip and disc-set strikers.
