not a kit, but just came across this:
250,000 pieces were used to construct the 550-pound model
I used to have a ton too, my mom either threw them away or gave them away while I was away in boot camp. Sucks, I might need to start getting some new ones!
I had a lego train I got for Christmas one year. If I could get any of them back, that would be what I’d want.
Along with the 50 gallon plastic container full of peices.
I have two different sets sitting in my fathers basement. Both are still together in boxes
THis set
and this one
Also found this site for buying old lego sets.
I was gonna say, you can buy old sets on ebay and on a bunch of sites. Some sites even have them new in box. When I went to college I sold mine and got about $1500 for my sets on ebay.
I will sell all of my legos including both train sets for 1200 obo
those trains were worth a fortune when I sold mine. So are the pirate ships
- rep. I’m finding a bunch of sets on here I used to have. I’m going to end up blowing a whole pay check on this website!
I know there was some sets i wish i never destroyed. There is one set i wish i still had the lego car wash.
Those train sets are awesome!
wanna buy them?
Half my room as a kid was a LEGO town. I have so many sets, its crazy. I wish i kept all the directions and pieces together. I build tons of custom shit with all my crap. Pretty sure the train set (first one posted) is still together in my cubby. Lots are together, just shoved in there years ago with layers of dust
