For those who may be interested in knowing;
The production of the pre-1600 series centerfire repeating rifles goes like this;
M46 (M94 action, 9.3X57) - SN from 501 to 14006 = Total production of +/- 13 505 rifles
M46A (M38 action, 9.3X57) - SN 40001 to 47873 = Total production of +/- 7 812 rifles
M46B (M38 action, 6.5X55) - SN 70001 to 73947 = Total production of +/- 3 946 rifles
M46AN (M38 action, 9.3X62) - SN N1001 to N1228 = Total production of +/- 227 rifles
M146 (M98 action, 9.3X57) - SN 20001 to 31440 = Total production of +/- 11 439 rifles
M246 (M98 action, 9.3X62) - SN N501 tp N727 = Total production of 226 rifles
M640
M646 (M38 action, 6.5X55) - SN 60001 to 60409 = Total production of 408 rifles
M646 (M98 action, 6.5X55) - SN 60501 to 60793 = Total production of 292 rifles
M648 (M38 action, 8X57IS) - SN 48001 to 57999 = Total production of 9 998 rifles
M648 (M98 action, 8X57IS) - SN 80001 to 89999 = Total production of 9 998 rifles
M649 (M38 action, 9.3X62) - SN 90001 to 92859 = Total production of 5 858 rifles
M649 (M98 action, 9.3X62) - SN 92901 to 97736 = Total production of 4 835 rifles
The 640 serie using "commercial" M98 (early ones have thumb cut-out, starts in 1948
M640 (M98 "Commercial" action) - SN 100001 to +/- 158 000 = Total production 58 000 to 60 000 rifles
The transition between the late M640 to the M1640 is complicated, as per HVA continued to produce limited 640 rifles until at least SN 163500
M1600 / 1640 production starts +/- @ 159000 and ends around 330999 but;
There is at least one very early 1640 with SN of 143###
The last 6000 rifles using 1600/1640 actions were sold to S&W and Tradewinds (H-5000)
So, the total 1600/1640 production is around 170 000 rifles.
These numbers are from the HVA Museum records and from what we were able to gather over 30 years of collecting.
It must be taken for what it is, an approximation of the total production, as per even the HVA Museum records contains errors / omissions.
