I maintain lists for all SEGA games and hardware released by Tec Toy.

The lettering was used to dictate the price range of the game in the stores, e.g:

-----------------------------------------------------------------------------------------
LOJA GAME SCORE - Agosto de 1993 (Game Score Store - August, 1993)

Prices in Cr$ (Cruzeiro Real <- not used anymore, replaced by Real in 1994)

Cartuchos Master System (Master System cartridges)

Carts 256K = 1.371,000
Carts 1 MEGA
Série B = 1.911,000
Carts 2 MEGA
Série A = 2.269,000
Série B = 2.423,000
Série C = 2.742,000
Série D = 2.949,000
Carts 4 MEGA = 3.240,000
Carts 4 MEGA ESPECIAL = 4.064,000

Cartuchos Mega Drive (Mega Drive cartridges)

Série A = 2.485,000
Série B = 3.280,000
Série C = 3.536,000
Série D = 4.397,000
Série E = 4.779,000
Série F = 5.832,000

After a through analysys of my lists, I can say for sure the first 3 number of the Model Nº represents the letters and size of the game.

Ps. This is 100% accurate in the Master System games.
Ps².With Mega Drive games only the letters match and the size of the rom match in most but not all cases.

Master System

021. = - (256K)
023. = B (1 MEGA)
024. = A (2 MEGA)
025. = B (2 MEGA)
026. = C (2 MEGA)
027. = D (2 MEGA)
028. = - (4 MEGA)
030. = - (8 MEGA)


Mega Drive

041. = A
042. = B
043. = C
044. = D
045. = E
046. = F
047. = G
048. = D
049. = H
050. = I
051. = F
052. = G; J
053. = B
