Slide rule & Harmonica. Original?

[buha]

Hello!

I found this slide rule and this harmonica for selling; tell me if they are original. Worth 25 euro both?

Can anyone help me?
Did I posted in wrong the category?

Hello and welcome, they both look like pre 45 if that's what you mean with original. I would say they are certainly worth 25 euro.
But do a google search on the Hohner, I'm sure there are good sites on it...

Finally, I'm their new owner.
