I, too, shall attempt prick free communication here... hopefully with more success.
As far as "re-making" the NSG Splatmaster, you'd better be pretty careful about patent infringement. That is a fully registered design and, if you look, you will see that it would be nigh impossible to legally "re-make" one of these without paying for a license to do so.
That said, if you DO decide to attempt this, I can put you in touch with the patent holder. As it happens, the patent holder also has a storage facility that is packed with original Splatmaster parts, from body shells, to all the guts.
Food for thought.
