Finding sailors from the Victorian era has been pretty difficult, but at last I have found what I needed.
Following on the lead given by Malamute that Redoubt has unarmed seaman which are not available in the on-line shop, I used the
Contact Form and requested the availability of figures.
Trevor from Redoubt responded and I ordered 10 sailors of his choosing as I didn't have a clue what he actually had. The transaction was conducted using PayPal.
Of the ten I received, two were of the same type. Here is a picture of the eight unique miniatures I received from Redoubt:

Note that all figures come without the head. I asked for the flat Victorian hat, but I also received a couple kepi's, so they can be used for the ACW as well. There is a nice variety of different faces with assorted beards, mustaches, etc. In height they compare favorably with Copplestone. Price: 1.05 GBP each.
Overall, very pleased with the figures.
BTW, does anybody know a manufacturer which makes suitable plank/ship bases to mount these on?
