Greenhouse - Crittall Type (Saltdean BN2)

I need to repair an old Crittall aluminium greenhouse, which are no longer made. They’re fairly easy to identify even if the labels have fallen off the tops of the gable ends because they have sloping sides and most don’t have gutters. If you have one you no longer want (any size will do) I will happily dismantle it and take it all away - including unbroken glass - to use as spare parts and/or to extend mine. I’m retired so can do this at any time to suit you.
Many thanks,
Greg
