I hope this doesn't come over wrong but i'll go anyways.
As a person looking to buy a can (or second hand one) selling the two parts separate for the beowolf is a bit off.
I can buy a new one for £142 and get both the link pipe and a new can.
You want £125 for the can (already overpriced for 2nd hand) plus another £65 to get the link pipe.

I'll get new with those prices as I will still have the lifetime guarantee and a new can.
Also you haven't posted the size 450 or 380? looks a round to me.
