225 degree angled trim for bay window

[toomuchworknotenoughtime]

I'm going spare. I have an old bay window with a timber cover or trim covering a 225 degree external corner gap where the two uprights have been placed. The timber has come away and warped and I cant for the life of me find a replacement part. It's too warped to get back into position. Can anyone point me in the right direction please to find a supplier.

Many thanks

Try searching for 135 degree (which is 360 minus 225), 135 is the more commonly used term in such cases

135 or 225 doesnt seem to make any difference. I seem to only be able to find 90 degree L shaped trims in timber though I have found some variable angle UPVC trims. I may have to go for that and given the woodwork is to be painted, paint that as well. I'd prefer timber if I can get it. Any views.
