Do we have any information on the use of this unusual slide rule arrangement? Any data available on the socalled "Polar" model? At first glance this may be a flight level calculator, but closer study suggests not so. Any information gratefully received. |

It's a very low end fake that looks nothing like any real model. |

This appears to be a rotating bezel for bearings, East and West of north and allows you to adjust the northing on the fly. Its not a slide rule as such. |
