P is for Police Department

Just a quickie tonight, it's a Hasbro dime store type, which is unusual in itself, but more so for having a folding roof, with no apparent purpose, by which I mean the internal compartment won't accept figures, there are no holes for torsos, and it may have had a small bag of candies, but it would have been very small?

What do you make of it? I took too many shots of the underside, and not enough of the top, but it's in storage now, I think? The hinged roof only invites damage? Marked POLICE DEPT., lengthways on the bonnet (hood), readable one way only, and HASBRO 1 MADE IN USA on the underside, it's a lovely shade of ultramarine!
