Original Grey Technic motor from 1977: 6216a

[Magnus Forsberg]

I think we should arrange it like other motors have been arranged.
One static, complete housing (without the axle) + one user adaptable axle.
motor = body (complete (casing+core)) + axle (complete (steel axle + plastic axle))

motor(complete) = (body(complete, made of casing part+ core part)) + (axle(complete, made of steel axle part + plastic axle part)).

We like to have the motor casing as a separate shortcut without the axle, and the axle as a separate part, so that a user could rotate the axle to any position he/she wants.

Design number 6216 has two element numbers:
621623 and 621624

This is LEGO's older way of creating a DesignID: Partnumber+colour code
621623 is a bright blue "Brick  2 x  4 x  2 with Curved Top"
621624 is a yellow "Brick  2 x  4 x  2 with Curved Top"

23 is LEGOID Bright Blue
24 is LEGOID Yellow


and in this case, they are unrelated numbers.

About the length of the axle - I'm not sure what you mean. Protrude -do you mean the front or the back ?

The steel axle, in 6216m.dat, is visible if you peek into the holes at the back of the motor. I think it is too long.
