if its the same . the markings are from India .
when the India clamped down on Firearms manufactures it became law that all firearms must go through all houses of the IOB , India Ordinance Board and the IOF , India Ordenance Factory
For inspection of records’ of manufacture and proof . They consider muzzleloaders to be firearms and the must meet the board standards or they cannot be sold in country or exported ..
their laws are very strict . One must have a license to , make , modify or repair and firearm or parts for firearms. Complete recourds for every part manufactured is also required .From what I have been told directly by the IOB , Firearms manufactures pretty much stopped the manufacture of muzzleloaders som 25-30 years ago as it wasn’t cost effective to do so .
I originally contacted the IOF concerning this very SXS and a direct question as to why the markings when there are no such marking concerning the Imports we see today .
The reply was that those being imported to day , do not have to meet the IOB standards as they are built as curiosities .
No Firearm my be exsported from india without meeting IOF standards . those markings on the barrel are the inspection marks from ther IOF and IOB.
Unlike other countries which we see alot concerning muzzleloading , India will tell you exsactly what their laws are .
some years ago," 2010 " i sent a few e-mails, including photos to the IOF a few days later i recieved replies from two diffrent IOF houses concerning the gun and my questions
Manufacturer is Insaf Ali and Sons, Jodhpur in Rajasthan State. All the guns are proof tested by the Central Government Proof houses located at Kanpur and Kolkata. (In this case at Kanpur) The serial number of the ML gun is 113.
Quality- Not good as compared to an English gun but one the best ML in India. ML gun production has stopped since last 15-20 years , they are now producing BL guns.
