TDB/ Fishbytes:
2 of them are just like that picture above (tulip style).
The other two are not tulip and are straight sided. The clamps on the straight sided ones are closer to the bottom of the holder. which leaves most of the rodholder cantilevered above the clamp.
Sorry no pics my digital camera took a dump this past fall.
