Thanks a6et, I haven't checked kerroby's listings. Slide bar covers were available from Casula Hobbies under Wombat Spares though they have sold out for the moment. I did get one set for the purpose of fitting my saturated 30 with a complete outback pack if I can call it that. Cowcatchers were mentioned as a future project on facebook I think.
A quick question for you or anybody that I've been meaning to ask for ages - What's the purpose of tailrods and why aren't they on superheated versions?
