Wanted : Sony WM-2 Walkman II Battery Holder & Strap(s)

Looking for a 2-D cell Sony Walkman II battery holder, in good condition. Have a WM-2 and almost all the accessories but this one is eluding me at a reasonable price. Looking for pay < $32 (shipped) for such a battery holder. Thanks !!

Also looking for a walkman II strap for the belt clip holder, with SONY buckles, if available. This is a 10mm japan-camera strap of nylon or polypropylene but the operative feature is - it should have two SONY buckles and at least 1 guide loop. I think this strap was also offered on WM-77. Price negotiable.
