Question

Asked by: Brad H
Subject: Patent Number
Question: In your propulsion page, you list Geoff Russell as having US Patent #2,090,404. But F.A. Parkhurst owns that patent, and it's titled,"A Machine for Extruding Plastic Material" and was published in 1936. Could you recheck this number and correct the error?

Thanks,

 Gyroscope.org is located in the U.K., and he was referring to GB 2,090,404... which is indeed the Geoff Russell patent.
