I agree it's a lovely machine, if a bit over the top design-wise with all the gaudy gold trim, but it is a great performer and will last a lifetime if not abused.
Does it have the original hose? That's the one big drawback of that series of machines - the last 1205, Golden Jubilee, Super J, Silverado, etc. -- the hoses for those machines are too short, too heavy, and quite thick. And they do not rotate at the machine end, making them awkward and difficult to use.
The single greatest improvement you could make to it, if it does have the original hose, to make it a top performer and a real joy to use, would be to replace the hose with a modern coiled hose that is longer and lighter in weight. Just do save the original hose if it's in respectable shape. It would be a creamy golden yellow in color with blue and white stripes.
