WW Ii Imperial Japanese Army Navy - SAKAE 21 ENGINE SPARK PLUG - A6M Zero - RARE

Description

You are bidding on a 100% ORIGINAL WW2 Imperial Japanese Navy/Army Nakajima Sakae Engine Spark Plug!
These engines were heavily in the A6M "Zero", Ki-43, Ki-48, and other fighter aircraft!
The Nakajima Sakae (栄, Prosperity) was a two-row, 14-cylinder air-cooled radial engine used in a number of combat aircraft of the Imperial Japanese Navy and Imperial Japanese Army before and during World War II.
The engine was designed by Nakajima Aircraft Company with code name NAM, as a scaled-down and advanced version of the previous NAL design (Army Type 97 850 hp radial engine, Nakajima Ha5).[2] The Imperial Japanese Army Air Force called the first of the series the Ha25 (ハ25) and later versions were designated Ha105 and Ha115, in the Hatsudoki designation system and Ha-35 in the unified designation system, while the Imperial Japanese Navy Air Service designation was Nakajima NK1, with sub-types identified by Model numbers; thus Nakajima NK1 Sakae 10, 20 and 30 series.
A total of 21,166 were made by Nakajima; 9,067 were manufactured by other firms.
Brought back by a US Serviceman, this sparkplug set is in FANTASTIC unused condition!  Some slight marks and wear, but nothing that detracts.  I have shown a similar one installed in the last photo.  Perfect for any collection, display, or restoration project!
