There is a "before decal-ing/after decal-ing" photograph (Figure 21, on page 60) of a custom-made (using MPC/AVI parts), scale-like model rocket (made using 20 mm and 15 mm body tubing) in the 1977 edition of "The New Model Rocketry Manual," by G. Harry Stine. It looks like the T15/20 balsa coupler ^might^ be 1" (or maybe exactly 25 mm?) long, but the picture was taken from a slightly elevated angle, so accurately measuring its length directly off the rather small image wouldn't be easy.

Many thanks in advance to anyone who can help!


The following Adapter table is from the 1969 MRI catalog, which is the predecessor of MPC/AVI, but many of the parts were the same. This table shows the T15/20 balsa adapter length at 0.75 inches/ 2 cm long.

Kind regards,
