As for knowledge of antiques, it's something that comes over time. When I started collecting for the Wall-O-Withnail, I was determined to only buy actual vintage items. Through internet research, I learned a lot from collecctors such as tips and tricks on how to spot a fake. By trawling auction sites and online stores, I learned what the "going price" for things was... then I'd haunt ebay until I could find the good stuff on the cheap! It's turned into a very enjoyable hobby.
Regarding the guys to gals ratio here:
I do love a good sausage fest, although I prefer getting wrecked and eating a pork pie.
