I agree it is a hybrid of DS and H grades. BUt the question is was it just a parts clean out gun or was the DS being evolved as time went by and they used the H grade as starting point. I have seen one other "DS" but it had damacus, G grade norm, barrels which were original to the gun. Figured they just used what was on hand at the time. Might have been out of twist and before steel barrels took over or they just cleanded out the bins and made the gun as a DS to get rid of old parts in stock.

I agree that Lefever has more variations than a few. Even with the books, good information for others and a open mind you can never say never with Lefevers. If it could have been done they most likely did make one of them.
