Braun has made two different travel shavers with the model number 370. They do not use the same foils. The foil for the older version has been discontinued by Braun and is no longer available. The foil for the newer version can be found at shaveroutlet.com. See link below.
Read the information there carefully to make sure it i for your version of model 370

I have successfully replaced the batteries two years ago in my Norelco 965RX shaver with two Rayovac AA Nicad batteries. Works as good as the original batteries. You must solder them in and solder a band (solder wicking works well) across the + and - terminals at one end.

The same cord can be used to plug into the bottom of the shaver or the cleaning/charging stand. Only one cord is included when the shaver was new.
I can't tell you if you can buy thse items in Seattle, but I can show you where to buy on-line. These items are available at shaveroutlet.com. You will need your model or type number to select the correct cord

On model 7775X the part you are asking about is not sold seperately. If yours has come off, it is because the plastic that holds it is broken. You will need to replace the head holder which includes this piece.
You will find it available at shaveroutlet.com. See link below
