Thanks, gents. Appreciate the positive comments.
jerryd--I'm sure you are correct about it being an SFO. I remember reading what the C & W stood for at the time I bought it, but for some reason that information did not get saved my hard copy paper files and I can't seem to access it in my overloaded cranial memory banks.
This S&M #69 Barlow is unusual enough just for having a Wharncliffe blade--don't see too many Wharncliffe Barlows...Sheepfoot, yes, but not Wharnies--hats off to the DFC for that brilliant idea (or is this Queen's answer to the GEC #77?); and, it's also got some most unusual stag handle scales as well...Gnarly, indeed! It's kind of amazing that someone was able to squeeze a keystone shield in all those bumps & knobs.
