I just got both of these drums at an estate sale. Based on the badges, the white marine Pearl Radio King is from 1944-45 and the Duco Radio King is from 1950-53. I will take them apart and clean them up. They came with calf skin heads which the resonant heads on both drums are ripped. Should I replace them with calf or go with modern heads? I have seen on YouTube that the drums sound very good that had modern heads on them. Thanks for your input!
