Now all I’ve got to do is locate the box.
Found it!
I'd forgotten how good these were. They're 54mm (not 1/35) with plenty of bits and pieces. DML even supplied a piece of thin wire for the ramrods.
The price on the box was especially good when I bought it years ago ... HK$ 30 (equivalent to £ 2.50).
With such quality and value for money, I'm going to have to have a go at a vignette very soon.
In answer to the original question, Brian hit the nail on the head suggesting Shenandoah Miniatures for anything that is not included in the kit.
Haversacks are already included in the box, together with cartridge and cap boxes, bayonets, etc, etc.
The only other thing that I can think might be required are blanket rolls, which would be best made from thin epoxy putty, rolled-up and shaped to the figure and its equipment.
Enjoy your modelling; I know I'm going to.
