WTB Northeast Airsoft Sten, or parts for any

I’m looking to purchase a Northeast Airsoft STEN MKII GBB gun. Or, if anyone has any parts, such as the barrel with front sight and it’s shroud from the MKVI that has the cooling holes in it. I have a MKVI with its Silencer, and love to be able to see if I could purchase replacement parts for the MKV to be able to switch mine over from a silencer version to a non silenced version. This is a tall order, but I’d think someone knows someone in Taiwan to be able to just purchase parts?
