Slider for bong?

Years ago I had a device that replaced the bowl on my bong. It might have been called EZ Sider but I'm not sure if that's right. It consisted of a long metal piece that had five one hit 'bowls' in a row. It came out of a bottom piece that attached to the stem of the bong for loading. You would take a hit and then slide it over a little bit and the next hit would line up right.
Does anyone know where to get one? I've looked for years but can't find one. I tried a revolving deal once but it didn't work nearly s well.
Any help greatly appreciated.

If you google six shooter bong.... You'll find what cha look'n for... They won't let me post a link... I'll get an infraction or banned.

The only thing that brings up is the revolving type, not the kind I described.
