TT shaft ID
I have some 712 MBs that are fitted with a TT shaft but no labels. Despite much research I cannot place the model, although the seem similar to XP but are not. Here are the step details for the 7i with pics included:
top of ferrule to 1st step = 7 15/16"
3 x 0.5"
4 x 1" (actually a hair over 1" but not 1/16)
2 x 1.25"
1 x 5/16" (this is what they call a 'speed step' right?)
1 x 4"
1 x 1/4" (another 'speed' step)
1 x 1 1/16"
1 x 1.5"
Some more data - I've calculated the approx weight of the shaft as 100g.
Here's what I've ruled out - Any standard DG, XP (blue label) range .
Havent been able find info / pics online for the old DG XP or SL or Dynalite? Could it be one of these? Help appreciated!
