    Paul, here are the specs for the suspension springs:

    For the "small" single contact model (Style 1100, glass dome on brass base), use a Horolovar 0.0040" spring cut to 5-3/4 inches long.

    For the "large" single contact model (may be in glass dome or 4-glass crystal regulator case), use a Horolovar 0.0045" spring cut to 7 inches long.

    For Horolovar springs in England, contact Patrick Wadge in Salisbury as follows:

    Patrick James Wadge
    83 Fisherton Street
    Salisbury, Wilts SP2 7ST
    Ph: 0172-233-4467

    For the Double Contact Models, there is no Horolovar or other temperature compensating suspension spring available. However, the originals were made of spring steel, and a ladie's pocket watch mainspring has been identified which works quite well. It is a Hamilton 6/0 #2521, 1.40 mm x 0.12 mm, cut to 11-1/4 inches long. These (or the equivalent) are available from most watch parts dealers who handle mainsprings.

    Hope this will be of help!!
