[Leica] Rolleiflex questions

[imra at iol.ie (Douglas Barry)]

I know there are people with Rolleiflexes on this list, so apologies as 
I commit heresy here.

I have three - a Planar 2.8 (up in the attic so inaccessible just now), 
a T s/n 2,117,7## from July 1959, an Automat s/n 1,251,9xx from Dec '51 
to Jan '52 - so decided to run run their shutters through the speeds and 
noticed the T seems slow at the higher speeds. Any ideas where I can 
find the most accurate way of checking the speeds for discrepancies? It 
probably needs a CLA, but that's a hunt for another day.

I also noticed that the T based on the serial number range on the 
Rolleiclub page is supposed to be in grey leather, but mine is black. I 
presume their list isn't gospel? On the Automat which works fine, its 
black leather has small brown scuff marks, so I suppose shoe polish will 
do the trick there, or is there a better remedy?

Thanks
Douglas
