No worries! Here's some more detailed photos for you guys to use. LMK if you'd like any others. For the 3 chamfers, I kinda just eyeballed their measurements which seem to vary between .060"-.070" but I'd stay closer to .060 as thats a typical size we often see in the machining world
I'm actually fairly certain that the Webley seen in ESB and the one cast and then used for ROTJ are one in the same, simply because they both have these chamfers on the D-bracket which seems to be a rarer variant.. They're most visible on the ESB blaster in the Cloud City hallway promo photos since they have a nice patina to them. That aside, even the butt of the stock on both blasters have the same unique sweeping "J" curve to them, and you can also see what appears to be left over glue residue from the ESB center stock greeble that got transfered over into the ROTJ stock during casting. I suspect that when they cast the flare gun for use in ROTJ that they simply filled in the large chunk of missing stock that’s seen in ESB for ease of casting, and thats why its not seen on the ROTJ Blaster
