A-1 Special or BHE Steel Shot Specials?

[Wild Skies]

I had a discussion yesterday with a friend, who's also a stockmaker and PGCA member, I mentioned that I have a Steel Shot Special (SG, SPL, DT) which appears to be unfired that I may be putting up for sale. He asked if it was a B-grade and I say no that I believed they were only produced in D-grade. He then told me of an acquaintance of his that had two BHE Steel Shot Specials (one unfired). Being suspicious of them being BHEs and realizing with all things Parker we never say never, I asked how they were marked and his reply was that they were stamped "Steel Shot Special" on the barrels. I said, Hhmmm, never seen nor heard of them marked in that manner nor was I aware of them built in any other grade other than a D. The conversation left me scratching my head -- and thus the question above.
