R44/R46 rollsigns and cabs

I visited the http://www.nycsubway.org website and found out that there may be two different types of R44/R46 pre-GOH side rollsigns. First type has route letter in color circle and terminals on black background outside and a route map on white background inside. Second type has route letter in color circle and terminals on black background outside and inside. Also, I found a photo of original R46 cab but I couldn't find photos of original R44 cab. I'm not sure if the control panels are same in R44 and R46. I think that GOH versions of R44 and R46 have different throttle/brake controllers.
