Ahh the wife, when I trimmed down my collection, I sold about 80 off which pleased her no end, until I told that I had 70 I was going to keep, at that point the level of deception dawned on her.
Well, an update. I am putting my Belgian M26/31 shell (with chin strap) up on eBay. I just bought a black-painted [police?] M26/31 with the lion's badge and "X. Buisset - Vilvorde" markings on the liner. The chinstrap has someone's name inked on, too. Paid $68.00 plus S&H! Strangely, this complete helmet (with chin strap) seems to weigh a lot less than my brown-painted shell for sale. Did the Belgians manufacture two types of M26/31? Who knows?
Well it can be a different manufacturer that might be the cause of a difference in weight. I would weigh them first to see if there is a difference.
