I've just replaced this window from my summer house. It might be useful in a shed. The wood is, I think a hardwood, and its all double glazed. The interior woodwork is in good condition but the outside is showing signs of age with one corner(see photo) having deteriorated and the paint has gone! The small opening has a crack in the glass.
So not beautiful but as I said, might be handy in a shed. The dimensions are window frame 181cms wide by 139 cms high. There is an outer frame which can be used or removed which gives it dimensions of 188cm wide and 147cms high.
Hope it can be used, else on the way to the tip. You're welcome to come and look, no obligation to take it away!
