I spent the weekend and today (Remembrance Day, Nov 11 in Canada) combing through old tubs of Lego for all the parts from a beloved set I had in the late 80s, early 90s. Only 3 parts missing though another dozen hours of searching might fix that - subbing for colour in the meantime.
Inspired by a video I came across where the subject is building a 5x scale version of the preceding set from 3D printed parts (here). I want to show my kids the power of patience and nostalgia; also I just want to see the set IRL again.
Should be pretty easy to guess which set this is.
As did I! I don’t know how one got the grey ones back in the day, but I have a couple in my childhood bucket 'o lego. The orange ones come with larger modern sets.
You could get them through their catalog.
