Yeah, to clarify: I ran a search at Scalemates on "sutphen" and it returned no records.
That doesn't mean that there isn't a kit, necessarily, just that if there is, no one has uploaded any info about it to Scalemates (remember, it's a wiki, relies on its members to post to it).
Now, I also ran a web search on "sutphen fire truck scale model", and that returned a large number of hits, but the models look like they're diecast, not model kits to build:

But it's a start.
