It'll be a great way for the boy to start. I started at a far younger age than he is. I was buying WWI stuff back in the late 50's when I was 6 years old. LOL
At one time, I had over 300 functioning milsurp weapons, with one dating back to the Revolutionary War. Best I can recall there were about 100 edged weapons and over a ton of antique ammunition.
I got fed up with constantly worrying about it all getting stolen about 10 years ago. I took two years off from work, went to gun shows and lived very well off that collection of stuff for two years.
You don't ever really own this kind of stuff. You just try to be a good custodian of it so some one else can enjoy it on down the road.
If I'd have waited till today to sell that mess, I could have probably taken 5 years off from the grind.
There are a lot of the toys that I wish hadn't pooped off but all I can say is. I had fun.
