I picked this up last week at a local auction, but I never managed to view it and left a commission bid. I was taking a chance but it did look lovely in the catalogue photo. When it arrived Christmas Eve I realised that the sac was solid and stuck to the barrel. I carefully managed to remove the sac with soaking and a gentle heat, but the pressure bar came out with it. For some reason I was expecting a J-bar but this seems to be a 'floating bar'(?). However, I can't quite work out how the bar fits to the lever, I have tried Googling but the advice is rather vague. I assume that the lever fits between the raised edges of the pressure bar, but can't quite work out exactly how it fits and stays in place. Can anyone provide some guidance?
