Your help on tangguh of these kerises!
 

Appreciate if you guys could help to determine perhaps authenticity or tangguh of these kerises. One with Longer Pesi(tang) and the other with shorter pesi(tang).Regards, Mykeris.

MyKeris, i don't believe there is anyone whose opinion i would respect on tangguh who would be will to make such an opinion based solely on these photographs.
As for authenticity, if you are wondering if there has been revisioning to these keris i would say possibly, maybe even probably, but could i be sure??? :shrug:

look like for me your putut kembar or some call it umyang jimbe is a keris "rombakan" a reshape from other dapur or other tosan aji.sory just opinion it is very possible im wrong.

Thanks, perhaps focus on whether its genuine or non-genuine.

IMO I would say that both are genuine putut kembar blades (made and intended to be putut kembar). The one on the left looks very old say early 20c or older (could be much older). But for the one on the right, I don't remember if I have seen a putut kembar featured with such a defined greneng, but then that is just based on my limited experience.

Thanks for your great opinions, Rgrds, Mykeris.
