I have 10 1/4" to banana custom cables built by Roxanne herself at STS Oakland. Found them stashed away in the garage. They are about six feet in length i believe. Im not sure 'cause they are all rolled up with cable ties. Mogami cable.
$150. for all ten. Shipping included. Continental US. Overseas, . . . more! LOL
pictures on request.
kind regards
