+1 to Andrew's advice.

There are two separate questions here:

1) is it worth restoring? I'd say a resounding YES to that one. It's always hard to tell from pics, but it looks in reasonable shape. Plus vintage Bokers are fine blades.

2) should you do it yourself or send it to a pro? Only you can answer that one as only you know a) what exactly you'd like to have done and b) whether you have the skill set to do it.

But again, back to Andrew's point: there is nothing at all wrong with cleaning the blade up, honing, and putting it to use.

Whatever you decide, good luck - it will be worth it.
