Could you have Pitch pine ..
... it can be very interesting as to what can be in old furniture should you get hold, as you've done of some, I've a sweet little knob on a box which had made which I was told was Teak form a Piano panel, all Igot was the knob ..
..
Very nice piece which you've turned, it may not need a finish, looks fine as it is, well done.
