I have tracked down the tulwar with the similar blade profile (its blade looks wider, although mine could have had several sharpening thus accounting for the slimmer look). The contour of the spine is identical, both have gorda/eye lash marks as well as maker/armoury (?) marks at the base of the blade (although not the same katar stamps). Here is the link
