Glued and screwed an ash repair section into window frame upright between N/S w5 and w6.  Removed as many of the remaining rusted screws and nails in the exposed framework around N/S w5 and w6.  Filled some oversize screw holes with hardwood toothpicks and PVA.

Ordered some grey enamel for the timber framing from Regal paints, which I thought was most appropriate and much cheaper than anyone else.
