The one pictures is an HS-3. You can tell the two apart by the stainless steel marquee topper. @jjhudgins, if you have this cabinet or are planning on picking it up and it has the ID tag on the back, I'd love a picture of it. I've been trying to find an HS-3 with the original model number tag for a long time now.
marquee topper comparison. The top is HS-3 and the bottom is HS-4
