Back in June 2019 I found on the sidewalk a large bin of LEGOs from the late 80's/early 90's and I started guessing the sets that came into the making of this bin. I initially focused on LEGO #System sets, but recently I did the same for the #LEGO #Technic parts I kept separately.

Here's the final list of the sets I rebuilt with the help of additional spare parts, in chronological order of release. I have several parts left but not enough to accurately guess sets or not enough to justify completing guessed sets. For example, I have a couple parts that were issued for a unique set each, 6987 - Message Intercept Base and 6598 - Metro PD Station but I'm missing pretty much all the other parts of these sets.
