Sand and repair as you go, then consider Sadolin Extra durable wood stain......its a first class product.
That sort of colour seems to be around the rosewood tint, I'd guess.

The frame and cill seems to be pretty sound as far as I can see, so make sure that any rain that runs down the glass panes cant get behind the glazing beads due to missing putty and so on.
Also see that the frame is well siliconed to the brickwork all the way round.
The frame does need a thorough sanding, of course! If there are any cracks or 'shakes,' consider car body filler to fill them up.
Personally I wouldn't go near traditional varnish - this Sadolin stuff soaks right in and leaves a satin sort of finish. For that frame, go for at least two coats though, and maybe another on the cill. The coating will be good for years!
