Make your own, It isn't as daunting as it sounds.
I've recently made approx 3ft for my 2" fowler.
Form wire of the appropriate size around a former of the require inner dimension of the link (Rectangular Aluminium worked for me) slit down the long side, form chain then use pliers to close up links, silver solder each joint.
You will end up with a chain that looks right.
