I have found some additional information that has bearing on how many rifles Laurania ought to procure and how quickly it should move towards replacing its ordnance inventory.
In testimony before Congress in 1917 (before the United States entered the First World War) it was held that European armies considered it necessary to have considerable stocks of arms – one nation calculating its needs at five rifles per man, another at four rifles per man; the justification being the need for wastage, those undergoing repair, and for those in transit to or from repair stations.
In the same testimony, it was averred that American manufacturers were capable of producing up to 3,000 rifles per day – after considerable expenditure of efforts. Another manufacturer contended that starting from a base level of 1,000 rifles per day he could not increase his output to 8,000 in less than eighteen months.
These data points have been useful in guiding my calculations. At least I don’t have to worry that I’ve projected too many rifles.
