I just looked at the pictures of that gun an hour or so ago. Still mostly Parker Bros. Still has the PARKER BROS. OVERLOAD PROVED markings on the barrel flats --

I have found the PARKER BROS. OVERLOAD PROVED markings used up into the 2369xx range. Some guns in the 236xxx range I've recorded with no proof markings on the barrel flats. The lowest serial number I've recorded with the PARKER GUN WORKS OVERLOAD PROVED barrel flat markings is 236490. I can't see a Remington barrel date code on the pictures I have of 236490. Serial number 236958 still has the PARKER BROS. OVERLOAD PROVED stamp, but has a Remington barrel date code of AD, A = March, D = 1935. Serial number 237149 with the PARKER GUN WORKS OVERLOAD PROVED carries a barrel date code of KD, K = May, D = 1935.
Likewise it has the Parker Bros. rib markings --
