Identify a Brompton

[bobworsey]

I have just been given a 20 year old Brompton, i am going to get it up and running but do not know which model it is? it has SRAM T3 gears (never come across before) and help much appreciated.

From the three cables going the rear triangle, it looks like an early 2000’s M6R (M style bars, 6 speed and rear rack) Could you post the frame number and I can date it accurately. Apart from the saddle all looks original right down to its green label tyres.
