Rocket box identification

[skippy]

Hi guys,

Got a box off a "mate" a while back and he reckoned it was a Rocket box, I'm suspecting its not but just wanted to check.

 

The numbers off the box are as follows

 

 

On tag   2821EM 6M 13 ( IF4)

 

Tail hsg  2821E 7A0400

 

Box body  2821E 7006D

 

 

Any info would be great, just want to know if its a Rocket or a door stop LOL

im guessing the only real way to tell is to pop the lid off count the teeth an work the ratio out

Pop it in first and turn the input shaft 1 turn and count the number of turns from the output.

Your looking for 3 turns from the output for every 1 on the input.
