Over at dads place, so finally had the opportunity to dig out his Birmingham made .177 FAC Tomahawk.
The rifle was bought from the offical Norwegain importer several years after production ceased in Birmingham,
perhaps somehwere around 2009-2011 if I remember correctly, but it has probably sat on the shelf there for some
time as it was one of few Birmingham made Webleys left in stock here at the time.

The first digit in the serial number is difficult to read as it is stamped a bit shallow, but under magnificatiion it looks like a 9,
followed by the numbers 17070, so the full serial number seems to be 917070.
