Some Anschutz single shot match rifles are more commonly seen than others. On the used market more 14xx rifles are posted on the EE than newer ones like the 16xx, 18xx, 19xx, and 20xx.
The basic models offered in the 14xx series, which were produced from the early 1960s to about 1974 or 1975, have similar versions in the newer series of rifles. The 16xx rifles have an X in the serial number and were made from about 1975 - 1980, the 18xx series from 1980 to 1988, and the 19xx from 1988 to the present. The 20xx series began in the early to mid-1990's and are still made. The latest model is the 54.30.
The barrel dimensions have generally remained the same, except at the muzzle where slightly different front sight mounting systems have seen some variation. For example the 19xx barrels are wider at the last two or so inches of the muzzle. This "swell" is dovetail grooved for mounting a front globe sight. Other models used a fixed barrel mount, a barrel block, or screws to attach the front sight. The front sight if present is of course removable.
Here is one of the most common Anschutz match rifles, the 1407 (66cm barrel). Going from memory, this one is from about 1970. Newer models have a more sloping forend, and the stock is deeper at the trigger guard. I've found that stocks with less slope on the bottom are better for shooting from the bench.
Here is the 1413 Free Rifle. It has the heavier, longer barrel (69cm).
The rifle above was designed for men's shooting as it is much heavier than the xx07 rifles. Many shooters use 1413 rifles off the bench, but a better model for bench shooting is the prone model, the 1411, because of its stock design. The forend is parallel to the barrel. The barreled actions of the xx13 and xx11 are the same with the only difference being the stocks.
Here's an ad showing the Savage Anschutz iteration of the 1407 and 1411. They were the same as the "regular" Anschutz except for the stamping which presumably had the name Savage.
There is also the 1409 and 1410 models. The former has the xx07 66cm barrel, the latter the 69cm heavier barrel. Below is a 1409.
The older 14xx rifles, that is those from 1964 and earlier, have dovetails only on the rear half of the receiver. The front of the receiver, forward of the loading port, is not dovetailed. For those interested in scoping these older models, there are a number of scope mounting options. I've always chosen to use BKL cantilever mounts, as seen on this 1964 made model 1408. As I recall this mount is the high model. They are quite solid and reliable. Also worth noting about the 1964 and earlier 54's is that they have one extractor claw (which works without issue), and a flat bolt end cap.
As a note of interest, the 1407 first appeared in the late 1960's (1968 or 1969?). Prior to that Anschutz had the 1408, which originally had a longer barrel than the xx07 (66cm), but it was a little slimmer, later, after about 1965 or 1966, the 1408 had the xx07 barrel. The 1408 shown above has that longer, slimmer barrel (the exact dimensions of which I don't remember). These earlier 1408's are distinguishable by their stock characteristics, with the completely parallel to the barrell forend bottom.
The 1408 name was dropped in favour of the 1407 by the late 1960s. The name 1408 was then given to the Running Boar model. Below is a 1408 EDS.
The Running Boar model has a thumbhole stock, adjustable cheek piece, wooden butt pad, round bottom forend, and barrel weights. They are not as commonly seen as many of the other models.
Since the receiver and trigger dimensions are the same in the 14xx series, the barreled action can be mounted in any 14xx stock. Newer barreled actions can also be mounted in the 14xx stocks, but the trigger area of the stock will have to be inletted to accommodate the newer triggers found on the 16xx and newer models. The 14xx barreled actions can be mounted in newer stocks. The round 54 action receiver has remained largely unchanged, but the triggers have not. Triggers is another subject altogether. The bolts can't be swapped between different series of rifles.
To sum up the 14xx series is the oldest of the numbered named models. There are older rifles, from the mid 1950s to the early 1960's that predate the numbered series. The more recent of these are indistinguishable from their almost identical models with the numbered names, which began in the early 1960's. The last two numbers in a model usually refer to the barrel length and stock design. The 16xx, 18xx, and 19xx series rifles are similar to the 14xx series, but they have newer stock designs and different triggers.
