Well it's a good idea to just buy a pistol to work with as an original Webley Flare gun will run you about $1200 bucks. For templates, you can just read my WIp and search on here for WOF's drawings for the accurate blueprints. As for the designation of EE-3, I not concerned with what it's called, I am building an ESB Boba, therefore need the ESB gun. That one does not have fins. It's simply a Webley with the same Graflex flash tube they use for Vader's saber as the tip, a scope added to the top, with molex connectors and v-8 model engine parts for greebs.
