Waveguide-choke-flange-through-mounted

Waveguide choke flange (probably RCSC 5985-99-083-0003) with gasket in place, (poorly) through-mounted on WG16. The recessed face of the flange and the end of the waveguide tube are somewhat crudely machined level. An imperfection in the brazing of the flange to the tubing has resulted in a crack exactly where the current on the inside of the waveguide broad wall should flow onto the recessed face of the flange.
