I have a fair idea who it is; not someone I know personally, though. The only hassles with these covers are no baffling, and a poorly defined surface to fit the cork gasket. Had a very good look at an identical unit recently. About $300 Aus is the sensible limit considering these aspects of function. But they do look good - if only the "Falcon" was larger!
p.s. I believe they are being repro'd now. About AUD$300 or so.
Cheers, Adam.
