Hi Chris,
I agree, second is quite likely European. Although I don't recall a trade blade pattern with a fuller and then a midrib like this. I'm more familiar with the flat patterns like the Peter Kull blades. Just a single fuller and then an entirely flat blade with a chisel like edge profile.
The leatherwork certainly stands out. I believe this type of leather is a good indication of age as it shows a different tanning process than the thin, modern leather usually seen on recent Tuareg work.
Hi Andy,
Glad you like these two.

I do try to get the odd looking ones - the book.. well....

Not the first time its been mentioned!
Cheers,
Iain
