Tulwar of the 4th Punjab Infantry with shortened blade.

[Chris Tubman]

Here’s a Tulwar that I recently acquired which may be of interest.
It has a shortened blade of about 20" length which appears to be very similar to a Prussian M1811 “Blücher” sabre that I also own or possibly a British 1796 Light Cavalry sabre?
When put together the curve of the blades matches exactly and the fullers are identical.
There are no makers marks on the blade but it shows a very short ricasso near the spine.
The blade tapers from about 10mm at the hilt to around 2mm at the point which has been ground to a hatchet form.
The hilt although very pitted still shows silver inlay in a six petal flowers and foliage design.
There’s a lot of open space around the short tang but what could be lead (?) holding the blade into the quillon block.
The quillon are stamped with the number 4 and P.I which would suggest the sword was used by the 4th Punjab Infantry who were formed in Lahore in 1849.
Any further thoughts in this sword are most welcome.
