Hi' it's the computer-illiterate here.

Thanks for the help, LP.
Yorkio, the link was made from a length of material used for lashing wiring harnesses. It had a braided core and plastic coat. I stripped the coating away and whipped the braid to the hook shanks. Nowadays, electricians, wiremen etc would use cable ties of some sort or another.
Marky, the 'tridem', for want of a better name, is possibly a variant of the once famous Ythan Lure, used as mentioned on the estuary of that great sea trout river, like PIB said. Cheers, Terry C
BTW, If you ever come across a ''Terry's Terror'' it is a different beast, and not invented by me!!
