My thanks to you David for sorting out my "email the board hiccup", as I can now post my answer to the board.

The information, including an old photo can be found by following the LINKS (from this site) to Sungreen, - Cinderford Pages, - Ruardean section, where it is listed as Royal Oak.

There is a fairly modern photo and some details about two brewery ownerships from the past etc, in Heather Hurley's book Pubs of the Forest. I can borrow-my-book-back and look it up if anyone needs the info.

The "Bag of Nails" is now a private house, off Pludds Court Road.
