What is this pamor?

Hello Alan,
To be clear the seller did not mean Tuban/ Mataram transition period but a blade made in Tuban style (form) during the Mataram era, but I accept your opinion that the blade was probably made recently as shown by the complex pamor especially. Any opinion if this blade was made in Java or Madura?
Best regards
