Vintage, 1950s Playskool Fire Engine No. 468 Set Rare Complete With All 5 People

This vintage play set from Playskool has all five of the first responders that came with the set, which is now so rare that many sources say there were three. Other sources identify the characters as Fisher-Price (they are not.) The fire truck is in very good condition. The ladder goes up and down, bell rings and wheels turn smoothly. The people are intact but the brim is missing from one hat and is broken on 2 others. The string to pull it has been cut to ~7”. The paint on the truck is bright and the lettering is clear. The truck could use a good cleaning but I haven’t tried to do anything to it. It is nearly pristine but is also 75 years old and I worried about damaging it.

I have not been able to find value references for a complete set with all 5 first responders so I have priced it based on the pricing of incomplete sets with significantly more wear and will consider any reasonable offers.
