I have on display my first model from 1965, and my newest 6 models.
I changed my focus a couple of times in between, quit table topping with my hundreds of tanks, had two plastic squashing disasters happen, and a couple of years ago just got rid of all the "off topic" aircraft like Spitfires and Thunderbolts, etc.
I had a lack of display space problem right up until I met Anne,,,,,,,,since then I have someone that actually enjoys the hobby with me, instead of one that hated the 3-400 models I had built and in boxes during my first marriage.
I got old and the stash got large just in time for me to have a "free retirement" pastime.
