Missing Mountain brushes after computer crash

[KuristZero]

Hey All!

I realise these posts are almost a dime-a-dozen so apologies!

I've been working on a rather large map over the past few years (200cm x 200cm) for a book that me and a friend have been writing.
Over the years we've been filling it out as we've wrote, but unfortunately my hard drive failed and I lost all of my brushes (Fortunately the map and book were backed up on Dropbox).

The past few weeks I've managed to track down most of the brushes we've used from across CG and Deviant Art, however I've hit an impasse.

I cannot for the life of me, find these brushes I used for the mountains in the image below.

The nearest style I've found to this is here (http://www.cartographersguild.com/at...1&d=1342705343) but they aren't quite the same style (the rock-face is different).

If anyone knows where these brushes came from and who the creator was I would be greatly appreciative as I really don't want to have to recreate the mountain layer from scratch!

Thanks again!
