Would anybody be able to offer some info on this plus maybe a rough price guide.
It is in original working order
Thanks

With chassis #511 is possibly a model 554 of 1936. Knowing the valves in it will help confirm that.

As for price, the general rule applies: it will fetch what somebody will pay you for it on the day you want to sell it. It's a market thing.

Value of radios depends on numerous factors including collectibility (rarity, styling, etc) and condition and completeness (of cabinet, and internals). Then there's the question of whether buyers are spending or sitting on their wallets.

Collectors are motivated by different criteria. There are some collectors who aim to get the entire range of an era; some aim to get every colour in a series; some collect only one brand/model, etc, etc.

Airzones of that era have fetched $300 upwards, again depending on the market at the time.

If you want to sell it, put it on eBay and be prepared to post it Australia-wide.

PS: If you don't know its operational condition, do not power it up just to see if it's working or not as you may do it irreparable damage.
