I'd say contact Neil Miller. He is a member on here, and also has his own website here.
I'm sure others will offer more help and advice, but when I asked the same question about a razor I was given, I was pointed in his direction.
Thanks,
His site was my number #1 go-to when I researched this subject, but unfortunately he is chocked up with orders right now, and I need to find someone else.
His website says:
SORRY! I am not accepting any custom or restoration jobs until the ones I have are completed.
