Major 2,
The Melbourne shows use to be pretty good for antiques, especially the winter shows.
Not long after I started collecting S&W's, the price went through the roof. Same with MH & Co. revolvers, among others.
However, if you are into the "Black guns", aka, "Modern stuff", one is in Paradise! These types of arms hold NO attraction for me personally!
This is my primary reason for not doing the show very often!
But still, it may prove to be a diversion for you when visiting the in-laws. I will try to keep you informed, if you like?
My best,
Blair
