Its probably actually a good thing to note that these were designed to fit my real webley and so I cant really guarantee a perfect fit on resin copies where theres likley a bit of shrinkage in the resin. One might need to add some thin plastic shim stock or something to the inside of the rear mount to get it to sit in the right place on the barrelThis thread keeps giving me more motivation to get a real webley...dang it.
Sorry perhaps my question wasn't so clear I meant with regards to the bit that clips over the barrel. And the width of the mount .The hole in the bracket is sized for use with a 10x32 socket cap screw and has a 5mm through hole with a 9mm wide counterbore (I did this to sorta copy whats seen on the ROTJ Hero since we’ve no good photos of this area on the ESB Hero). The bracket itself is 17mm wide. And I sized the mating inside holes on the clips to fit a 5/16th x 1/2” long threaded aluminum spacer (these are readily available at any local ACE hardware store)
All the other holes are sized for a M5 cut tap so set-screws can be added
