Rick Barnes's Big Bertha BT80 Upscale

This is my upscale of a Big Bertha to BT80-sized tubing.  That's not to be confused with being a clone of a Super Big Bertha.  SBB is also BT80, but there are a number of differences, including in proportions.  The SBB isn't long enough to be true to upscale, at only 36.5".  This model is more correct at a little over 38", the body tube is one piece, rather two joined, and it has a 29mm motor mount rather than 24.  I finished it to match the original 1965 rendering of Bertha (using Excelsior decals), though the two black fins are my own interpretation of it.

Diameter:2.6 inches
Length:38 inches
Style:Upscale
Type:Scratch
