A Moray jacket type tank holder and some breathing stuff that goes with it as per photo. Obviously used etc, but looks OK, but would obviously need to be tested & operated etc and checked before anything serious is done. Might be good for the swimming pool learning etc. The breathing mouth piece says ATM 500A Waterlung. The jacket on the inside does not say what size or model it is. The inside black plastic part of the tank holder measures approx. 395mm long if that's any help. Obviously sold as is where is, for someone who knows about these things and can sort it out, do it up, or whatever. If you can not do that or do not know about these things then please do not bid. It is as complete as the photo shows. If its not in the photo it is not in the auction and I have not got it. Apart from being faded and use wear etc, I can not see anything wrong with it, but again, I do not know about these things. Helpful watcher says "I'm not if you are aware, but these are vintage & have not been made for quite some time. Parts are no longer available, so unserviceable. Only useful for display purposes at best. icon -thanks for that. Have added a photo of the shoulder area which is cut off in the main photo - & its shows a space where you can see the inside ?? bladder ?? so again, have no idea if it should be like that or have a cover, and have no idea if it will hold air or what ?? Thanks. 914 ref4261
