Ju 87 Stukas

[BigDuke66]

Checked the Stukas in the German OOB(OOB16) and found some things that look strange:
-Ju 87G-1 Stuka(ID 120) still has the MG17 of the older Stuka models. AFAIK the only forward weapons for the G series were 2x 3,7cm BKs.
Also I wonder why the size is now 3 not 4 like all other Stukas, especially as the G-1 is just a refit of the older D Series Stuka so size shouldn't differ while the speed change from 4 to 3 looks OK as the pods reduced the speed.
-Ju 87D-8 Stuka(ID 487) not sure if the Armor HEAT value has any effect in the game but I wonder why it is halved from 10 to 5 on the D-8 version compared to all other Stuka versions.
Also I wonder if the designation D-8 is given on purpose or just a typo, the main variant was D-5 and the D-8 was just a D-3 upgraded to D-5 level with flame dampers as the only new thing on it for night operations.
