| 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.
