Minimoog key spring

I am trying to source one of the copper coloured compression springs for a white key, bottom F, for my 1974 Mini.

Everything else is fine, lost the spring while the wooden cabinet was being refinished by a friend, looks great but now no bottom F…

Is anyone able to supply one or know of a source?

Thanks Cliff
