I wish you luck on that. I recently bought a rifle from an estate which was fitted with the base for a Griffin & Howe side mount and the base for a Lyman 35 receiver sight.

Although I sent photos of both the top slide of the G&H mount and the slide for the Model 35, at first there was no positive reaction. Eventually the scope and top slide for the G&H turned up, but the heirs insisted that they were not part of the sale price and wanted to be paid, so I reluctantly agreed. However, the price they wanted was less than a new set of G&H rings would cost, so that sweetened the deal considerably. The slide for the Model 35 is still missing.
