Identifying Spanish Mausers
Models 1893 and 1916
Model 1893s and 1916s are basically very similar variations on the same theme.  Information on Spanish-made Mausers in the literature is contradictory and often difficult to follow.  The purpose of this website is to clarify what variations exist (there are six major ones that I am aware of - see the site map on the left) and help you to identify which one you have.  The first step is to determine if it is in the Model 1893/1916 "family".

All Model 1893's and Model 1916's have a rib on the left side of the receiver wall, and the bolt face is squared off at the bottom.  All were originally chambered in 7mm Mauser.  Serial numbers usually consist of a single letter, or "2" and a single letter, followed by anywhere from one to four numbers (usually four).  Examples:  E6578, 2N3375, etc.  The picture below shows a Model 1893 action with bolt.
The Model 1893's have 29" barrels, straight bolt handles, and no thumb cut in the left receiver rail.  Oviedo Model 1893's have a crown, the year of manufacture, and "Fabrica de Armas Oviedo" on the receiver bridge.  The more recent Oviedo Model 1893's (after about 1918) have an oval gas escape hole in the left side of the receiver.  Imported Model 1893's (from Germany and Belgium during the 1890's) usually have the Spanish crest and year of manufacture on the receiver bridge as well as the manufacturer designation on the left receiver wall.  The picture below shows a side view of a full length Model 1893. 
The Model 1895 carbines are similar to the regular Model 1893's, except that the barrels are shorter (about 17"), the rear sight is shorter, and most are stocked all the way to the end.  The bolts are bent as shown in the picture below.  They were also imported in the 1890's, then manufactured at Oviedo, and the markings are nearly identical to the Model 1893's.
The early Oviedo Model 1916's have the Oviedo crest and year of manufacture on the receiver.  After the Spanish Civil War, unmarked 1916's were converted from existing Model 1893's and 1916's, presumably at Oviedo as well, or at least that's my theory as of now.  These rifles lack any markings to indicate where and when they were made.  The existing markings were presumably ground off, and the rifles were given new serial numbers.
There are also Model 1916 carbines.  The action is identical to the Model 1916, but the barrel is approximately 17", and the rear sight is of the carbine variety.  See the picture below; note that it looks much like an 1895 carbine from the right side.  The distinguishing features (thumb cut and gas escape hole) are on the left side.  All of these reported to date have four-digit serial numbers without a letter prefix.

The Model 1916 rifles (see the picture below) are also similar to the Model 93's, except that they have shorter barrels (about 21"), a thumb cutout in the left reciever rail, an oval gas escape hole in the left receiver wall, and either a lange vizier or tangent leaf sight.  Most were manufactured or converted from older rifles at Oviedo, although some were made in the Barcelona area during the Spanish Civil War.
