Steel Casement Windows wanted.

<div>G'day all, I am planing a renovation/extension in the coming future. I was hoping to pick up second hand steel casement colonial bar style windows. I have called a number of window recyclers and they have all stated that they are very hard to come by? Lots people want them but no one gives them to recyclers??:doh: Can anyone help?
I love the idea of keeping all the windows the same. I have found alternatives but this is in wood and brand new $20,000 at least.:)(
