Need some dimensions. Can anyone help?

I'm trying to scratch build the barrel cleaning rod tube on a jagdpanther. My first prototype was done using best guesstimates from photos. Unfortunately when offer the prototype up to the model it doesn't look "right" . I was hoping someone out there might have some accurate measurements of one that is "right". The diameter of the tube and its overall length would be a great help. Cheeers

From my HL Jagdpanther the cleaning tube measures 127 mm long with a diameter of 11.1mm at the tube and 12.8 mm for the end caps. Sax

Thanks for the fast and detailed response. Much appreciated. At 1/8 a piece of 22mm copper tube will do the job nicely. Cheers Sax you're a gent.
