When the Texas SA, Inc. was sold to the Reese family of Illinois in November, 1974 the M1A receiver serial numbers had been stamped, at most, up to 0046XX. References: 1) my personal phone interview with Elmer Ballance 2) the entire Tom Buss personal notes collection on Ohio Gun Collector Association shows from September, 1971 to May, 1976 3) Tom Buss' documentation on M1A receivers and barreled actions purchased by him between December, 1971 and June, 1975 from both Texas SA, Inc. and Illinois SA, Inc. 4) my discussion with Illinois SA, Inc. Customer Service Department regarding the start of their M1A serial number records 5) my private e-mail correspondence with several owners of M1A rifles in the 002XXX and 003XXX serial number ranges 6) the occasional instance of slightly soft receivers beginning at serial number 008XXX based on information provided by M14 gunsmiths Ted Brown and Tim Strait 7) my interview with the shop foreman of Hillside Manufacturing from 1976 to 1996 and 8) my interviews with the shop foreman of Valley Ordnance from 1993 to 1996 who quoted from the Valley Ordnance log of M1A receiver serial numbers and associated manufacture dates in his possession during the interview.
M1A serial number 009XXX is not a Texas M1A receiver based on the sources cited above IMO.
