Mark IIC+ transformer and chassis questions

[hammer]

Recently purchased a C+ serial number 13,0xx. It is a sixty watt with reverb and no geq. The board is RP11A, + sign above cord and mb initials beneath. RCS initials on bottom of chassis. The side of the chassis has S 21. I thought the reverb models were SR? Would this have been something that was added later or did they just miss putting the R on there? Also the power transformer looks like it is either 00-162318 or 00-162310. Can anyone tell me 1) Which power transformer do i have? and 2) Is it a factory reverb or was the reverb added? Thanks!!

The RP11A circuit board was the factory reverb circuit boards so I doubt the reverb was added later. The most likely explanation is the "R" was mistakenly left off of the "SR". The amps serial number falls in the factory C+ range. 00-162310 would be a factory power transformer for a 60 watt C+. 100-162318 would be a 100 watt/simul pre + power transformer part number (105-162318 100 watt/simul factory) so those would be very unlikely and there was no 00-162318. I know some of the numbers can be hard to read. RCS initials on the bottom of the chassis are Randall Smiths.

Thanks!! On closer inspection it is 00-162310. I suspect they just forgot the R on the chasis as well.
