There seems to be quite an interest in a listing of the application base codes for the old original Lyman tang sights. I have looked through many vintage Lyman catalogs, and I have compiled the listing that follows. I am pretty sure it is complete for the time period it covers, but if anyone has any additions or corrections, please feel free to offer them up (I may have inadvertently missed something). Many "special" tang sights to fit rifles of unusual configuration in the tang area were also made, and I will not try to address those. Lyman also made a number of sights to mount on the cocking pieces of various military rifles. These tang sights do not have published application codes as far as I have been able to determine.
These are the several variations/types of tang sights that were made, and I have tried to briefly summarize them as follows;
1. No. 1 Combination Tang Sight (first variation) – patented Jan. 28, 1879. This sight has a thick base and a knurled thumbscrew on the right side of the upright pivot. The real early sights did not have the flip-down peep window, but that feature was incorporated before being replaced in 1884 with the Second Variation.
2. No. 1 Combination Tang Sight Second Variation – patented May 6, 1884. This sight has both the JAN. 28, ’79 and MAY 6, ’84 patent dates stamped on the base of the elevation upright. The knurled screw was replaced with a hairspring that allowed the elevation stem to be locked in the upright position by a spring loaded detent. It was replaced in 1905 by the No. 1A
3. No. 1A Combination Tang Sight Third Variation – patented July 25, 1905. The “A” suffix indicates the addition of the locking lever on the left side of the upright pivot. This sight was in production until 1955.
4. No. 2 Combination Tang Sight – introduced in 1894 and it was intended for Match and Gallery rifles. It is identical to the No. 1 Second Variation except that it has a screw in aperture disk instead of the flip-down peep. Several different aperture disks were available (each with a different diameter peep hole). The larger the outside diameter (OD) of the disk, the smaller the diameter of the peep hole. I believe that seven different sized disks were made (from 3/8” to 1” OD)
5. No. 2A Combination Tang Sight Second Variation – introduced simultaneously with the No. 1A, and is the same the No. 2 except for the locking lever.
6. No. 15 Windgauge Tang Sight – patented August 23, 1887. This was the first sight that could not be folded down like the No. 1 and No. 2 Tang sights, and because of that fact, it was a poor seller and was discontinued in 1906.
7. No. 29 Windgauge Tang Sight – patented March 6, 1900. This sight has a square stem piece, and could not be folded down like the No. 1 and No. 2 Tang sights. It was discontinued in 1903 due to complaints by shooters of frequent damage to the sight (due to not being able to fold it down).
8. No. 101 and 102 Range Control Tang Sight – patented March 9, 1915 and April 18, 1916. These were the first sights to offer click adjustable elevation. The elevation thimble had ten graduations (marked 0, 2, 4, and 8 with a detent position between each mark). The No. 101 had a flip-down peep, while the No. 102 utilized a screw in aperture disk.
9. No. 103 Windgauge Tang Sight – introduced in 1916. This sight is the crème of the crop. It features a micrometer (half-minute per click) elevation and windage adjustment, and uses the screw in aperture disks. It is highly sought after by serious target shooters. It has the same locking lever as the No. 1A and 2A, and was discontinued in 1955.
10. No. 47 Windgauge stem. I do not know when it was introduced, but it was made to replace the standard elevation stem on the No. 1, 1A, 2, and 2A Tang sights. It allowed for very precise windage adjustment by use of a thumbscrew (1/4 turn changed the impact ½” at 100 yards with a 30” sight base), and it uses a screw in aperture disk like the No. 2 or 2A. If a complete sight was ordered with this feature, it was referred to as a No. 52A.
The following list is what I was able to dig up… I hope that it helps to clear up any remaining questions that you may have.
