In answer to the above question I would suggest to contact the
conservation department of

    the Museum Boerhaave
    Lange St Agnietenstraat 10
    2312 WC  Leiden
    the Netherlands
    +31 71 21 42 24

Paul Steenhorst will be the person over there. They have a large
expertise in treating and (re)lacquering instruments (very beautiful
collection!). To my knowledge they did research in shellac varnishes and
can motivate in technical terms why and how one should re-apply shellac
and not more modern materials. As for the mentioned ingredients--there
are no modern equivalents, nature cannot be copied only imitated--you
could try the larger suppliers to painting and furniture conservators. A
good guess is:

    Cremer Pigmente
    D 7974 Aichstetten
    0 75 65/10 11 + 16 04

hope to have answered your question, yours
