Right, no cotton mesh, so possibly a reprint? The paper seems naturally aged. I bought it back around 1980's I suspect (or whenever eBay was getting going) and I think it may have come to me from New Zealandicon? I kept no documentation on the purchase.

I will probably just put on MilSurps for a little while, then migrate to Gun Broker or possibly even eBay...from whence it came.

Thank you Woodsy for the insights and explanations. Cheers.
