You're dead right of course. I was forgetting that the collectors value ain't quite what the users value was. As a matter of interest, these slings were made by Irvine and just the parts alone, from aerolex in Devizes (? correct me if I'm wrong) cost about £120 or so. If the storeman ordered 10 to keep his stocks up, he'd get a shirty reply from the production control office at DSSD at Bicester!
