[Motorola] KVL identification

[Glenn Little WB4UIV]

I have a KVL that is in a MX300 case.
This tells me that it is a T30xxy.
The keypad is 16 buttons implying that it is a XL.
The boards are TRN4835A and TRN4834A. This implies that it is 
probably an A or B and probably cannot be upgraded.
The ROM is TRN4974A.
It has a TRN6777B hybrid.
is this a T3010 or a t3011 and is the suffix an A or B?

Any help appreciated.
