I love the attention to details, especially on the British import knapsack - seen original photos of confederates wearing these and once they've removed the wooden box they tend to bulge out between the leather corners. Look forward to seeing more British kit being worked into the confederate models. One really eye catching one to do would be the pattern 42 cartridge pouch which they used during the Crimean war - its a huge monster of a cartridge box but in that way very distinct!
Are you entirely sure? They were in fact importing 1859/1860 pattern boxes, which are thick, but not that huge. I think you may be thinking about them but confusing dates with pattern 1842 US boxes. And yeah, P1860s are already done.
I'm sure the later pattern were smaller and more frequently imported so yeah your probably already on a better track! No the ones I was referring to are definitely British pattern, used them for the minie rifle through 54-55 in the Crimea and I've got one for my Crimean impression. Anyway I'm just stitch counting at this point; the details you've already gone to looks brilliant and no need to add in kit that would have been the exception and not the rule.
Well in this case I'm rather genuinely interested in this pattern. I'm no specialist in most of things between 1815 and 1861, but I've got a copy of this Pierre Turner's book on the british equipment, and for la nd troops it seems to be quite inclusive normally, yet for infantry cartridge boxes there is a huge gap between 1805 pattern and 1856 and later 1859 patterns. I sort of thought it to be reasonable since that's exactly what was happening with the canteen or mess tin for instance, but it's possible it misses another pattern out indeed.
