What the easiest way to get the glass out now - scraping the putty out

the pane out (although I did want to use the original pane for the
glazier to measure)?

A double glazed panel in a wood frame should be set in a flexible mastic -
not ordinary putty as that will cause it to flex and fail. So it will
require cutting round with a sharp knife - there should be plenty
clearance between panel and wood for this.

I had four replaced yesterday, the joiner used a soft rubber gasket
specially made for re-fitting double glazed units in wooden frames.

The unit is apparently made slightly smaller and stood on spacers with
a mini window sill that provides a drainage path beneath so that the
unit can't sit in water.
