Chinese Type 58, 67 and 68 stick grenades

[batonroundcollector]

what is the difference between these models, which seem visually very similar? is the Type 68 a dedicated practice version, or is it just that I have seen a practice version of the Type 68 that in fact has it's own designation? does the red-brown painted head denote it as practice?

From the infos I have :

	T58	T67
Diameter	48	50
Length	203	204,5
Weight	535	560-630
N.E.W.	100	100
Delay (sec.)	2.5-5	3-3.7

I don't know the type 68


Cheers,
