Hello,
indeed i have seen the repro ones, but would like to have a matching pair and i would like to keep the original one.
So this is why i was looking for another original.
i seems to have found one, from a good seller. Hopefully will be with me soon. Again i found it on e-bay.
i am not sure about the internals, but a visible difference from the H and L, is that looking at them from the coil side the L horn coil wind clockwise, the H tone wind anticlock wise.
in attacchement the Windtone manual, hopefully of some use.
Best,
Eddie
