 The 12.7 mm Akan m/39A was basically a rebarrelled version of the 13.2 mm Akan m/39A. The gun had all the same proportions and technical details but was rebarrelled to the more common Browning .50 cal (12.7 x 99 mm) ammunition instead of the worldwide less common Hotchkiss calibre of .52 in (13.2 x 99 mm). Since 12.7 mm ammunition was cheaper to buy than the cost to produce new 13.2 mm ammunition, all 13.2 mm weapons were re-chambered during the post-war era, and after 1950 basically all Swedish weapons fired the new cartridge. Other specifications remained unchanged.
-Commonly mistaken with the Browning M2 (due to the same calibre) the Akan m/39A featured a modified electrical firing mechanism rating it from 600 rpm to 1500 rpm. The gun was used as secondary armament for tanks with a reduced rate of fire (720 rpm) as well as standard armament for a variety of Swedish late- and post-WW2 aircraft such as the Saab 18, Saab 21, and the predecessor FFVS J22B with a rate of 1080 rpm.

 The Akan M/39A (12.7mm) is a rechambered variant of the [[Akan m/39A (13.2 mm)]] which is itself a Swedish licensed version of FN Browning M.1939.
-Sweden ordered the FN Browning M.1939 in the original 13.2mm Hotchkiss in 1939 after expressing interest in 1938 and would get a license to produce the design by LM Ericsson in Stockholm. After the end of World War II, however, Sweden realized the 13.2mm Hotchkiss was too expensive to continue purchasing. However, they have recently purchased the [[J26]] (surplus [[P-51 (Family)|P-51 Mustangs]]) and thus they had the [[M2 Browning (12.7 mm)|M2 Browning]] in .50 BMG from these aircraft which was designated the [[Akan m/45 (12.7 mm)|Akan m/45]]. As a result, the Swedish decided to convert their Akan m/39s to .50 BMG in 1947. The conversion was a simple matter of swapping the barrels leaving them to continue to have a stock of 13.2mm barrels and cartridges for a few years for use in live fire exercises. While the .50 caliber was arguably a downgrade, the Swedish Air Force by this point had switched to 20mm cannons in their main fighters. The [[T18B]] coastal bomber was the last aircraft to use the .50 Akan m/39A as a weapon and was retired in 1969. In 1950s, the Akan m/39A became a training weapon for Swedish fighter jets such as the [[J28B]] (export version of the de Havillard [[Vampire (Family)|Vampire]] fighter jets) and the [[J29 (Family)|J29 Tunnan]] fighter jets. The last weapon to use the Akan m/39A as a trainer weapon in place of their cannons was the [[J37 (Family)|J37 Viggen]] series which was retired in 2007.

-The 13.2 mm FN Browning was developed by FN as an improved version the Browning .50 in (12.7 mm) air-cooled MG53 aircraft machine gun. Improvements to the original design included: making the weapon lighter, increasing the rate of fire and offering it in not just 12.7×99mm Browning, but also 13.2×99mm Hotchkiss,[10] the latter cartridge effectively being a 12.7×99mm Browning cartridge but with a caliber of 13.2 mm (0.52 in).[11] The 13.2×99mm Hotchkiss cartridge was the initial cartridge developed for the 13.2 mm Hotchkiss machine gun, being replaced by the 13.2×96mm Hotchkiss cartridge in 1935,[11] and was thus used and produced by a wide variety of countries in Europe. To further improve on the design, FN developed a high-explosive shell against air targets for the 13.2×99mm Hotchkiss cartridge, purpose built for the 13.2 mm FN Browning.
