I hesitate to add this post as it is somewhat off topic and it may not add any clarifying information, but here goes...
Here are some advertisements that tend to support Strawstalker's comments on the Santa Fe Hawken, Leonard Allen, and Uberti.
This ad appeared in the October 1978 issue of
Buckskin Report.
This next ad appeared in the February 1979 issue of the same magazine.
The ads are identical except one says Allen Firearms Co. and the other says Western Arms Corp. It appears that the company names were interchangeable at this time. In fact, if you look closer in the circle behind the Allen Firearms Co. banner, you will see it says Western Arms Corp. On the other ad it says Allen Firearms Co. in the circle behind the Western Arms Corp. banner. Both ads say "in cooperation with Aldo Uberti & Company" and show Uberti's trade mark. I don't know if this indicates that Uberti was in partnership with Allen in Western Arms or not, but there certainly was a close relationship.
At the bottom of the ads you will see the statement "Western Arms and Aldo Uberti are presently building a factory in Santa Fe, for the purpose of building fine firearms in the United States. Full production is expected in early 1979."
This next ad ran in the April 1979 issue of
Buckskin Report. Note there is no mention of a factory in the US making these.
In November 1979 and February 1980, John Baird wrote columns about the Baird-Weber J&S Hawken rifles that Western Arms and Uberti were planning on producing in the US factory. In the first column, Baird specifically mentions that the sample he examined while visiting in Santa Fe was made in Italy. Something happened, and other than a the samples made in Italy, the Baird-Webber J&S Hawken never went into production.
IIRC, Western Arms Corp. got into legal trouble with Olin Industries over trade name infringement about this time.
By July of 1980, these ads were being run in
Bucksin Report.
The copy in these ads would suggest that Western Arms Corp. had been dissolved and new companies set up to sell remaining inventory that bore the Western Arms Corp. markings.
The Santa Fe Hawken in my possession has Western Arms Corp over Santa Fe, NM stamped on the top flat. On an oblique flat it has the caliber stamp and serial number. On a side flat it has the A. Uberti C. Gardone V.T. Italy stamp and Italian proof marks. On the bottom flat is stamped "Black Powder Only - Made in Italy". The manufacture date code is AE, indicating it was made in 1979.
My interpretation of all of the above is that the plans that Allen and Uberti had to build a plant in the US did not come to fruition, possibly due to the litigation with Olin Industries or financial problems or both.
That said, I also have a Western Arms Corp. Jedediah Smith Commemorative Hawken that is marked on the tang "No. 91 of One Thousand". The barrel is also marked with serial number 562, .54 cal, Italian proof marks, and on the bottom flat, Uberti's trade mark and Black Powder Only. The date code in the proof marks are also AE indicating it was made in 1979. There is no "Made in Italy" stamp!
My Santa Fe Hawken and Jed Smith Commemorative Hawken rifles are essentially the same except for the barrel markings and some of the metal finishes. All of the parts of the rifles--barrel, rib, thimbles, lock, triggers, trigger guard, butt plate, nose cap, escutcheons, and stock--are exactly the same.
One possible explanation for the Jed Smith Commemorative markings and finish differences is that it was shipped from the Uberti factory in Italy to the US unfinished. Allen could then add the Commemorative stamps and numbering and put the final finish on metal parts and stock.
The conspiracy theorist in me makes me wonder if Olin Industries, which owned the license to build and market Winchester firearms at the time, was more concerned about Uberti getting a manufacturing foothold in the US than it was about the trade name infringement. Colt took similar legal action against American Western Arms when AWA and Armi San Marco merged in the 1990's. The end result was about the same in both cases.
Enough conspiracy theories.
To get back on topic, here is a picture of my Ithaca Hawken.
And for comparison, here is my Santa Fe Hawken.
They are very similar, but not exactly alike. The Ithaca has the Cherry Corners lock/hammer, breech and tang, triggers, guard, and butt plate.
The Santa Fe has a slightly different lock/hammer and breech snail. The triggers are different also. The stocks are similar, but have subtle differences.
What I always found interesting is that they both have walnut stocks, German silver escutcheons, and white metal nose caps--an aluminum alloy on the Ithaca and pewter on the Santa Fe. The rear sights are near identical, also.
From what I can tell, Ithaca started production about a year before Western Arms/Uberti. Did Allen send Uberti one of the first Ithaca Hawken rifles off the production line and have Uberti copy it?
Oops, I'm back on conspiracy theories.
Last comment, then I'll go away.
Stantdm is correct that Ithaca bought Cherry Corners (1976) then Navy Arms took over the Hawken line from Ithaca (around 1979) and started making the Navy Arms/Ithaca Hawken with the same American made parts that Ithaca used. Navy Arms later started importing Uberti Hawken rifles and marked them Navy Arms/Ithaca Hawken. These later rifles are essentially the same as the Santa Fe Hawken rifles. So there are two versions of the Navy Arms/Ithaca Hawken out there--one American made and one Italian made.
