Hi Keith,
Yes, of the three South and Central American M.1912 contracts that DWM sent to Steyr in the 1912-1914 period (Mexico, Colombia and Chile) some or most of each of these contracts were in Steyr warehouses awaiting shipment or in production in August of 1914. If you check the sticky on Steyr factory production records in our Steyr Mannlicher Forum, you can find the M.1912 production numbers for each country, which all in all, up to mid-1914, total around 94,700 rifles, which breakdown as the following totals:
1. From the Mexican contract: 33,002 rifles
2. From the Colombian contract: 12,160 rifles
3. From the Chilean contract, 43,107 rifles
It may well be that these rifles were the ones that were actually delivered to their clients. It's hard to tell, especially when you match these up to M1912 rifle figures which John Walter lists in his book "Central Powers Small Arms of World War One". He lists Steyr M.1912 production which was (apparently?) on hand in the warehouses awaiting shipment in 1914, which was sequestered in 1914 and gradually taken into A/H Army service. The Chilean contract for 43,107 rifles appears to have been completed early, in the 1912-1913 fiscal year, which may be why we see so many of these on the US collector market. Most were likely delivered and little used.) More may have been made in Steyr's 1914-1915 fiscal year. Production figures for M1912's after August 1914 do not appear to have been published
Walter's book provides these details on quanitities of rifles per country which were in production or storage at Steyr in August, 1914 which were purchased for Austro-Hungarian service:
1. From the Mexican contract, 67,000 rifles in 1914 (p. 153)
2. From the Colombian contract, 5,000 rifles in 1915 (p. 160)
3. From the Chilean contract, 3,000 rifles in 1916 (p. ??)
It would seem that the reason that so few Chilean rifles saw A/H service during WW I was that they were the first order completed and most may have been shipped before the outbreak of the war.
I would also add that there is a fourth variety of the M1912. In A/H service, as was noted above, these Steyr Mausers were known as the "M. 14 Repeating Rifle". There is a version of this rifle in the US Army Ordnance Museum collection at Aberdeen Proving Ground, MD, which was made at Steyr in 1914, but which lacks any national crest. It is just marked "MOD. 1912" on its receiver ring. I have a photo or two of this rifle which I'll post below. It has a very low serial number so it's an open question as to how many of these may have been produced.
Regards,
John
