One other thing on the field grey M15's Bosko is that they often have natural coloured liners. The M1895s and earlier all have black dyed liners. Dyed on the hair side of the leather (smooth)...the flesh side which is rough is left natural. Modern leather is dyed on both sides which gives away many repro liners and chin straps. When I make a new liner for a helmet, I have to dye the hair side black. The liner also has to be made from the same type of leather as were the originals and tanned in the same way. So, to do it right is not a simple process. Brian
