I used to have the Marx Blue & Gray set, it was my all time favorite. also had Fort Apache and a WW2 set as well.
About age 12 - 13 started painting metal soldiers. Then at 14 I began getting into sports, girls, dirt bikes then cars and all that other stuff just kind of went away. ( I think Mom gave it away during my college years ) About 15 years ago I started to get into the metal toy soldiers again, Britains, Conte, FrontLine, King & Country etc. I don't attempt to paint them anymore so I buy sets already completed, my aging eyes wouldn't stand the strain. Don't tell the wife, but I figure I've spent over $3,000 on my "toys". BTW, a company has bought the rights for some of those old Marx sets, they go for $200 & up.
