Here's a Paragon RA-10 regenerative tuner and its matching DA-2 detector amplifier. If powering the radio up and seeing if it will work isnot one of your priorities, then you won't need to do anything except find a few feet of shelf space for it in your collection.
Here's an uncommon and beautifully made tuner and matching DA manufactured by the Boston Scale & Machine Co. in the early 1920's. Overall condition is very good. Both the tuner and the DA are original throughout, with no restoration, no repairs, no issues.
