SERIAL NUMBERS Deciphered Toshiba my 14

I find little information on understanding serial numbers yet so much can be found in them if understood. I welcome all comments to better understand this situation. Here are my observations from my 14 Toshiba's.
A. Serial number always in battery compartment
B. First is a number second usually is a Letter.
I am guessing these have something to do with regions or ? I have two KT-R2 one from Canada has a 8 as second identity while other unit from USA has a Z. Just a hypothesis that if you all can check and add your TOSHIBA model number with ORIGIN if possible to help solve what serial number means would be great.
C. Very interesting is that 11 out of 14 my models have third number always a 6. Thus I assume from observation that numbers after the 6 are the actual number of units and number of each unit.
D. It appears that in most models except the late 80's KT-4551 number 45,233 units all others are under 10,000. Is it possible that Toshiba did not make 100's of thousands like sony often did? If serial number of units made after first 3 digits is region based then my assumption here that Toshiba was especially in first 4 years a low production manufacturer then I could be wrong.
E. Appear if my hypothosis is right then my KT-RS1 was the # 882 unit made and KT-4067 the #1491 unit made making these additionally valuable.
NOTE PLEASE DO ADD YOUR TOSHIBA MODEL AND SERIAL AND ORIGIN IF KNOWN to this post and add your own observations. The QUEST for knowledge continues.
