{REQ} Stock Recovery for official B324

Hi all,

I have successfully unlocked bootloader, flashed TWRP recovery and rooted my device MT7-L09. My question is where can I get a hold of a copy of the stock recovery for the official B324 lollipop release? Or is there a way to make a backup of it still on my device now?
I'm kind of new to this, so please bare with me :)

Thanks!
