I recall something about Hydrazine [sp?] used in early German rockets as an 
oxidant. <?> You know, "T-stock" and "Z-stock." ...Or something along those 
lines.

Says it all for me. <G>  Thanks for the input!!!

And now you find S. America home? Stentor sounds like a name I've heard before. 
(Maybe I'm showing my lack of age here?) It's a US company, isn't it?
