Not an expert on the issue, and certainly not in ASE's from the 50's, but I really like them and regret not buying one, when available.
I believe they were finished in the SO shop, and had the same barrels as the other SO's, with Boelher steel.
They are regarded by many as (much?) better than the current DT10's, not sure this is true, but I certainly like them better.
Beretta Gallery has a few of them brand new, made with the last actions in stock at the factory. They were built and numbered as a special and last edition, and if it wasn't all the trouble in buying a gun in the US and bringing it here, I sure would have kept one.
