Hmm, Looks like we will be refurbishing similar DP's at nearly the same time! I picked up a Canedy-Otto Royal 18 last Jan 10th!
I'm not sure if mine is pre or post Cincinnati acquisition, but I suspect Pre.
My Label was painted over and after a careful stripping of the overcoat, they had clearly sanded the label prior to painting... not much left but what remains does not resemble yours... the SN is still visible since it was stamped though 3811...
I'll be starting a tread on mine and I'll post a link if you are interested.
Does yours not have the gear rack table lift? the spring loaded "counterweight" is a nice feature, but I'm looking at getting/making the pieces for the same lift for the head. (both use the same active parts.)
