Mike,
After long last, it appears that your question is addressed via a documented reference book. I am working on reading through it now and slowly jotting down notes. There is a section that goes into the initial orders of these short rifles between 1930-early 1931. It is way more than 1,000!

I am heavily abbreviating the content from Jędrzej Korbal’s book. Additionally he was able to follow up with me on some clarification questions. I will present it below.
Available documentation from military archives allow for partial reconstruction of the number of Wz.29’s in the Polish Army’s inventory during a limited number of individual years.
On June 12, 1930, the Military Engineering Supply Plant (WZZI) issued order no. 48/Kraj.30-31 concerning the delivery of 46,669 Wz.29's (note for the purposes of this text, I am not differentiating between K29's and Wz.29's). All weapons were to be delivered by March 15, 1931, produced in accordance with the following "batches":
• by June 15, 1930 - 4000 rifles,
• by July 15, 1930 - 4000 rifles,
• by August 15, 1930 - 4000 rifles,
• by September 15, 1930 - 4,000 rifles,
• by October 15, 1930 - 5,000 rifles,
• by November 15, 1930 - 5,000 rifles,
• by December 15, 1930 - 5,000 rifles,
• by January 15, 1931 - 5,000 rifles,
• by February 15, 1931 - 5,000 rifles,
• by March 15, 1931 - 5669 rifles.
As a side note of potential interest, the value of the contract amounted to 12,649,632.45 Polish zloty, or 271.05 Polish zloty per rifle.
On July 7. 1930, the order was amended (final delivery schedule deadline remained the same):
• by July 15, 1930 - 3473 rifles,
• by August 15, 1930 - 2000 rifles,
• by September 15, 1930 - 5600 rifles,
• by October 15, 1930 - 5100 rifles,
• by November 15, 1930 - 5200 rifles,
• by December 15, 1930 - 5,200 rifles,
• by January 15, 1931 - 5600 rifles,
• by February 15, 1931 - 7200 rifles,
• by March 15, 1931 - 2796 rifles
Additionally, on July 17, 1930, WZZI reported that another correction had been made to order 48/Kraj.30-31, transferring part of the production to the Warsaw Rifle Factory (PFK Warszawa). Thus, the delivery schedule was corrected for the second time:
• by July 1, 1930 - 3473 rifles from FB Radom,
• by August 1, 1930 - 1600 rifles from FB Radom and 400 rifles from PFK Warszawa,
• by September 1, 1930 - 5600 rifles from FB Radom,
• by October 1 , 1930 - 5100 rifles from FB Radom,
• by November 1, 1930 - 5200 rifles from FB Radom,
• by December 1, 1930 - 4600 rifles from FB Radom and 600 rifles from PFK Warszawa,
• by 1 January 1931 - 4100 rifles from FB Radom and 1500 rifles from PFK Warszawa,
• by February 1, 1931 - 5200 rifles from FB Radom and 2000 rifles from PFK Warszawa,
• by March 15, 1931 - 2100 rifles from FB Radom and 696 rifles from PFK Warszawa.
IMPORTANT NOTE: From discussion I had with the author after reading this booklet, it was not clear from archival documents if PFK Warszawa assembled the Wz.29 rifles from FB Radom parts, made Wz.29 parts themselves, etc. however it is assumed that this production of rifles from PFK Warszawa in 1930/1931 involved the production of K98-29 "conversions", where small ring K98 carbines were reconfigured into Wz.29 pattern short rifles. This was a short lived project, as a K98-29 conversion of an existing carbine was 1/2 the cost of producing a Wz.29 from scratch, and not cost efficient in the long run.
