It must do (if it is original)
# A vertical shutter-release button
# Preview Lever
# Two (2) Control Dials
# AE-Lock Button
# Green Button

The battery grip is not avalaible for home delivery so there is someone that can buy it and ship to me in Italy? Another in this forum from who I must buy his b.grip(but it haven't all the options of the original) told me that the cost for the shipping is 9£ so I wish pay 44+9=53£ with paypal to someone that can help me . It is a gift for my nephew.
Many thanks to all can aid me.

Many thanks to Snootchies for the refund. Good luck for the sale.

Excuse me Snootchies but I am new of this forum so I wanted to say the problem and that the battery grip can be sealed to other.

I have just write to Snootchies because if it doesn't has the ring for adjust times and diaphragms as the pentax battery grip, AE-L, I made a great mistake because my nephew want with these option like the pentax battery grip . I have readden "identical to proper" and so I believe with these options.
I hope that can refund me (i'have paied with paypal) beacuse I really am a serious man ; but I believe like the pentax battery grip even is produced by other manifacture.

Ok I can buy it, I wait the cost of the shipping.

Excuse but I am italian and in the italian forum we write mp..
