A White for sure. Some new and refinished parts are still available. Im not sure about Gonics but some Whites can be rebarreled with OEM or even an aftermarket barrel blank. IIRC White used Wilson and Clerke barrels.
As mentioned Gonics have a proprietary bore (small). Only Precision Rifle sells the sabots. 451 Conicals are available from Bullshop and NoExcuses.
