Thats presumably one of those flat spiral wound jobs? I think they call them tensator springs.
Google that for a supplier. Afternote google tensator springs. Pages from the UK – several listed.
Also Ivan Law at MES will know because he used to get them for the Dore Westbury. He doesn’t do the DW any more, but hes very approachable, and he will know where to get one from.
