Rich, congrats on a job well done! [ Guests cannot view attachments ] Those sight glass fittings are a tricky business.

Have been in contact with Wayne about the missing sight glass on his Play Boy (Empire 92) engine. I think they did the same thing on that model, that is, discontinued the spherical sight glass elbows in favor of cylindrical ones. Like you said -- probably just a cost savings. I prefer the looks of the spherical ones. I'm planning to use 3/16"(5MM) sight glass tubing for Wayne's engine, and probably make some of the spherical elbows.
