Any knowledge about my John Barber?

[Flamez]

Dear all,

Maybe some of you can help me to gain any knowledge about my John Barber straight razor i found in my Grandfathers heritage.
As far as i understood it seems to be manufactured by JB. Thanks to Neil Miller‘s explanations under http://straightrazorpalace.com/razor...ly-1800-a.html .
As you will see the edge not immaculate and i‘m wondering if i should keep it as it is or let it restore by an expierienced cutler.
I‘m thankful for any information about my razor.

By the way. Below i also attached a foto of the case the razor was in. Well, razor and case do not match, but does one of you know this company „Prima Schweizer Rasiermesser“?
