I smiled when I read your post because it brought back memories of several years ago when the forum seemed to regularly find itself hosting long and detailed threads about such things as clerical garb, clerical headgear, honorific titles, episcopal regalia, and a variety of other form, style, and terminology based differences in various of the Eastern and Oriental Churches. I tried my best to track down a few of those that I thought might give you some start points. I did come up with this thread, which may be of some use:www.byzcath.org/forums/ubbthreads.php/ubb/showflat/Number/389579

. It is the personal and private collection of Dieter Philippi, an entrepreneur and CEO of a German telecommunication firm. It is the largest single collection of clerical heagear in the world, I believe, and is pretty fascinating.
