Mark on a (T.N.I.?) Klewang

[ruiter58]

Hello,

I am Dutch and a klewang collector (meaning the Dutch model klewang) I think I have finally laid my hands on a TNI klewang but to be honest; that is only based on a star. The blade is marked with a star and has a 4-digit number (2198) On the left and on the right of thus number are two small marks which resemble the footprint of a crow. The 2198 number also appears on the hilt.
1- can anyone confirm this is or can be a TNI klewang?
2- About the crow footprint (2 to 3mm in size) => I am sure I have seen these before but I have no idea where or when and on what weapon..... Can anyone tell me more on these markings?

Thanks, Ron
