injecterators. any info or help out there ?

I purchased a set of used rough shape, injecterators. the carb looking injection system. waterman and Mitchel I think made for a few years.
things look neglected and some pitting rott.
I asked a local fuel injection shop to make them new again. they accepted the job, but never touched them for the past year. so now I feel I have to figure out how to freshen them up and learn how to rebuild them.
so far I need new needle seat parts, squirter diafram parts.
id like to verify and know parts are correct, like cams on boosters, and top squirters.
I could use any info and help to figure this set up out.
then I will need jets,nozzles, lines,and pump.
thanks for any help.
