In coming years, I do not believe the Greek rifles with "B" pinned floorplates will suffer much detraction in value. The Greek rifles are a well-documented and accepted collection venue within themselves. The rifles have all U.S. parts and, in the long run, should have value competitive with comparable U.S. overhauled rifles.
A drilled and tapped rifle, on the other hand, will never recover much value.
