Pulp Figures preview Harpoon cannon

Pulp Figures have posted a preview of a Harpoon cannon they are contemplating releasing.

From their announcement:

I’ve built a separate version of the Harpoon cannon from PHP-13. Instead of it being the sole possession of the Gyro Raiders, this would allow others to use it; regular sea-going pirates, whalers, used car repo men etc. It would come equipped with a motorized winch. There would likely be two or three in the pack.

I’m not sure if demand would justify releasing this model so any opinions would be welcome. Please forgive the quality of the scan, it was done quickly on my flat-bed scanner/printer.
