This is a top hung DG window frame in pine - possible someone like Magnet as the source. It's done 23 years so I perhaps should be grateful that just one of the six in the extension has deteriorated.

It's the bottom bar (of course!.)

The rotted area is some 12" x 1" x 1" - that of course is at least !!

I see 5 options

1 See if there is a replacement frame on the market - suspect unlikely

2 Get the local joiner to build a new frame

3 Build a new one myself

4 Cut out and patch with wood

5 Cut out and patch with car body filler while perhaps I do #3 over the winter.

Replacing the bottom bar is really a no-no as the frame will have to be out of the window for a period and this window faces the main road.

How good is body filler for this type of bodge ? My thinking would be to anchor it to some screws into the less rotten wood.
