It looks like they've renamed it yet again to the 234RC
No. The 234RC has an integrated Manfrotto-proprietary RC2 clamp. I had the 234RC, had to sell it and get the 234 when I switched to Arca plates. The 234 has a reversible 3/8"-16 + 1/4"-20 stud for the clamp of your choice, or direct camera mounting.
The 234 does appear to have been discontinued, that's unfortunate.
The 234 was a great advice, and I use it with the C-10 clamp.
I don't know why Manfrotto stopped selling the plain clamp given they have so many products (234RC, window mounts, wall mounts, etc.) based on it. I was actually lucky to get one new from Adorama!
It can be found used under the alternative name 3232, and there are many sellers on eBay who sell it combined with an Arca Swiss plate (of indeterminate origin and quality).
Kirk used to sell a 234 with their clamp as the MPA-1 (http://www.bhphotovideo.com/c/product/555294-REG/Kirk_MPA_1_MPA_1_Swivel_Tilt_Monopod.html
). Those come up on Ebay or Fred Miranda from time to time as well, so you may get lucky. You can switch the tilt orientation from front-back to side-side, but it requires an allen wrench to reorient the dovetail. Used to have one myself but stupidly sold it, and their new model (MPA-2) and RRS are overkill for my medium-sized Induro monopod.
This thread inspired me to look again, though.
