Further information has been reported from official sources about this weapon, previously
referred to in Tactical and Technical Trends, No. 21, p. 6.
It appears that to date the only 76.2-mm piece reported mounted on the 38 light (t)* tank
chassis is a long-chambered version of the Russian field piece 76.2-mm FK (Feldkanone,
field piece 36 (r).*
The long-chambered piece and the Russian light field piece are identical
except for the following differences:
||76.2-mm as mounted|
on 38 (t) tank
||76.2-mm FK 36 (r)|
|Length of chamber (approx)||
|| 28 in||
|| 15 in|
|Chamber volume (approx)||
|| 3,600 cc||
|| 1,780 cc|
|Maximum range (estimated)||
|| 15,000 yds||
|| 8,000 yds|
Both pieces have Russian markings; however, the only known long
cartridge case ammunition is of German manufacture.
It is also of interest to note that the same cartridge case is used in
the 75-mm Pak 40 (antitank) as is used in the
long-chambered 76.2 mm.
*The letter t stands for Czech; r for Russian.
