WOW what an incredible find! And the price certainly was right!!
The gray and black braided hose was original to the earliest version of the Model XI. Later into the run of the XI, the machine-end connection was made to screw into the front cover. At one time I had two XIs, one with the stick-in connector and one with the screw-in. I still have the screw-in version. You can see that machine in the link below.
