If you go to any chandler you can get very light weight high quality pulley's that will self lock.
The gambrel in the picture is David Strettons from Donningto deer management. I think they are about £18 but a bit on the small side for reds, I have used one Fallow Though. The pully shown in the kit I bought recently for £12.50 at a game fair as a spare, it's strong but a bit bulky and won't self lock. David Stretton sells the hooks too but any S hook will do.
Take a look at any on-line dinghy sailing shop ("Chandler"). Take a look at the 'micro' ball bearing block from Harken, Holt Allen, RWO, etc. For sika a 4:1 or 5:1 pulley system with 5mm string is fine. For roe sized deer a 3:1 is adequate. For the rope, buy an supple easy-to-handle rope, rather then a super low stretch one - it's easier on the hands and folds more easily into your jacket pocket.
They also sell simple stainless steel hooks which serve to either hold a gambrel, or can act a a one-leg gambrel (this works brilliantly for me).
If the assembly gets mucky, I just chuck into the washing machine.

It also happens that I sail, so I had a bunch of usable parts sat in my gargage.
Should there be a photo or am I missing something

Hi Guys Thanks for the info
Actually sourced the marine cord and two Harken twin pulleys from my local marine chandler in whitstable and have sourced a cracking stainless steel folding gambrel today as well.
Job done
Many thanks to you all for your help
