Greenhouse Glass 2x2ft (CW8 Barnton)

Hello, does anyone have any spare panes of glass that are 2ft x 2ft please. My greenhouse is missing like 20 panes. currently using some wood on one side and some plastic a neighbour gave me. also missing 3 triangles. The Greenhouse is an old 8x6ft aluminium frame greenhouse i recovered from someone years ago. If you have any let know, will happily come help take them off a disused greenhouse too. Thank you for looking.
