I was on the hunt for a Standard Sony SRF-A1 AM Stereo Walkman and just by pure luck I was in a place yesterday that sells everything and anything that did not sell at estate & auction sales and found this SONY SRF-A1 Coca Cola promotional Walkman from somewhere around 1985. (Probably didn't sell sooner because I found it at the bottom of a box under some clothes, it pays to look) It is in very clean condition and almost perfect. It came with the belt clip, the coca cola headphones I already had.

Not too sure if it is rare, collectible or worth much but I thought it was cool and bought it. I probably will keep it for awhile, but who knows....I have a few other hobbies and they ALL cost money. There is never enough cash  

All the best, Mike

Great find !!  Promotional Walkman or Radios always adds greatly to value of item although I am not familiar with the portable small Radio only market have about a dozen but not purchased anything in years.  Its the right RED color and in great condition.  A keeper for display.  There was a great topic few years back on promotional Walkman that you may want to look up.
