Hello Newbie!
You're doing pretty good for a 'new guy'
Just as Jens has noted spot on, your tulwar is a very nice example of fighting tulwar on latter 19th to very early 20th century, and Rajasthan quite likely for manufacture. It seems the diamond grip shape on the hilt and the simplistic squared langet have been sometimes associated with Sikh examples, but definitive qualifications on that are elusive. I have spoken with a number of Sikhs in trying to determine any particularities that would exist on a weapon to define it as Sikh, but usually the 'wry' reply was always, "if it was used by a Sikh...then it is Sikh".
On that note, I would welcome any observations from our members or readers that might enlighten that topic.
Getting back to your tulwar, in my opinion the markings are most likely associated with either armoury or possibly even unit markings. The reason I suggest this is that they are placed in the same key location at the back on the blade near the hilt that was consistantly used by British makers on swords throughout the 19th century. I once owned a pair of solid metal tulwars made for native cavalry troopers in British Raj units, that were manufactured by 'Mole', the well established Birmingham maker later incorporated into the famed Wilkinson. These were stamped 'Mole' in the exact same location at the back of the blade.
It is well known that British native cavalry regiment contingents favored the tulwar, especially of course the Sikh and Rajput warriors that comprised considerably the ranks. I would suspect this tulwar to have been produced under auspices of British stores contractors and issued militarily within native regiments during the British Raj period, likely in the time period suggested.
The axe is also extremely interesting, and is actually not a combat weapon, but a ceremonial weapon that was interestingly often used in northern India as a standard in battle (much in the same way as the Islamic 'alem' , or huge leafed spear head was used). See "Battle Axes" (James D. Gamble, p.83) for identical example. Gamble notes that these typically were overlaid and chiseled with figures similar to those found on Indian ceremonial temple axes known as 'catri'. It seems likely that information on these might be found in data on Rajputs or Rajasthan (such as James Tod).
Looks like you've pretty much scored some original items from the colorful period of the British Raj in India!!
Very nice!
All the best,
Jim
