What an enormous expenditure only for the magazine boxes.

There were at least 18 (caliber related ) differently dimensioned boxes .
Every box either with floorplate leaver release or button in the trigger guard bow.
And moreover every type with DST or single stage.
Because they simply did not insert an DST into the otherwise identical bottom metal , but made it integral with the bottom metal you must quadruple the 18 caliber related dimensions and we have round about 72 maschine setups for the bottom metal alone.

That is only one aspect why the Commercial 98 Mauser rifles are so reliable and highly estimated up to now.
