Just got this locally off craigslist. This set is the exact same set I had when I was a kid. It was the only "big LEGO set" I had. My dad was a fireman so maybe that's why he got this one for me.
I was poking around CL for car stuff when a LEGO ad came up, opened it and saw this picture! I was like, "No way, that's the exact set I had when I was little!" Got it with a LEGO helicopter and a bunch of spare parts for $15. He even still had the instructions! It was the seller's when he was a kid, made in 1977. Not bad to share a bit of my child hood with my kids.
