Ok a few more photos after reading the replys again from the original post.
Mine seems to have the plastic pawl and have the cast ally ajuster. Anyone want to have a guess at the year of make???

Sorry about so many posts and photos but I am a little excited smile [Linked Image]

Also one of the chains seems very loose as you can see in the photos should it be like that??? and can someone also let me know what you think of the condition of the sprockets.
