Inaba no kami Hiroshige Signature help

Can anybody validate this signature or post some pictures to compare this with


Comparision

There one here with papers. http://www.finesword.co.jp/sale/touken/htm/462_500/467/467_hiroshige.htm
Also one here http://www.juwelier-strebel.de/asien-kunst/japan/verkaufte-artikelsold-i... I can't read the site but also seems to have papers.
It's worth remembering that the signature is only part of the whole, and to look at the features of the blade when making comparisons.

Thank you

Thank you
