I picked up a large vintage lot recently primarily for the Classic Castle and Space sets, but it also had several Expert Builder sets, a couple of boats, and a building or two in there also. Of the "scrap" pile, I've managed to piece together the following:
709-1 (95% complete - needs color restoration)
316-1 (90% complete - needs color restoration)
585-1 (about 75% complete)
733-1 (was about 80% complete, but I've been swiping bricks to complete other sets, mostly Classic Space)
844-1 (99% complete - missing the rubber belt for the rear rotor)
I have books, instructions and identifiable parts for a few other Expert Builder sets and what appears to be a large red structure that I have not pieced together yet.
At what point does it become pointless to try to restore these old sets? My completionist mindset has me putting everything into Bricklink wanted lists that's missing from pretty much anything and everything I can identify with few exceptions, but in the case of 585-1, for instance, there are pristine examples on eBay right now for less than $80. So even if I decided to restore them to resell them, I'm not sure it's worth the effort. My LEGO enthusiasm says, "New life to old bricks!" but my logical mind says proceed with caution.
Thoughts? I'll admit, building that helicopter (844-1) was a solid reminder of why they say "Expert" on them, but it was sure a nice trip down memory lane.
Oh, and first post. Hi, everyone! :)
