I can see some differences between yours and the one I just retired from work but I think they are about the same vintage. Mine is all Black.
I dont know the model number but it is a nice BC. It was a working/play unit for around 15 years or better. Now it has been retired to strictly a play unit. I like it for travel because it will fold up into a nice little tube for easy packing.
I cant tell for sure, but does your hose have a dump at the top? Mine doesnt, just the hose going directly into the BC.
These things are tough. We can really beat the crap out of equipment and DUI, Sherwood and Zeagle always take it without any problems.
Mine is still in great shape and had I not replaced it with a Tech Id still be in it.
What did you have to give for it?
