Hunting for a Lovat Scouts Style Bonnet

[Guthrumironhead]

Greetings all,
I am trying to locate a bonnet of Lovat Scouts type in size 7 1/4, or 58cm. I don’t need an original as long as it looks the part, navy blue with navy torie and white and navy dicing with untied tails. I had always intended to have a custom Mackie made at some point, but that’s not possible now with the company no longer making traditional headwear. Please see the pic, courtesy House of Labhran.

I appreciate any help I can get.
