I picked up this Aiwa which is an All Weather unit with a difference. It has a case which you pop it into which makes the Aiwa weatherproof and you operate the machine as normal as the controls and headphones are reachable through the case It is quit heavy though and the Aiwa itself is plastic casing with a radio as well the controls on the top of the unit are operated by flicking a black flap to access the controls
Nice pick up, that case is very cool, I love the oddball units, I'll have to see if there were patents on that case.
