Leon...
I think it is time you rented a storage shed somewhere....U Stow It in Canberra currently have 3x3x1.5m storage for $100pm...maybe there is something close to you that is reasonably priced?
That dryer is far far too rare for you not to have it.
The last time I saw a pair (not sure if they were matched) of full sized Simpsons was 20yrs ago. That was a 1966 push button you have and a similar vintage Simpson dryer.
