Hi Danny,
This looks do-able .
You wouldn't have the missing piece would you ?
If you don't perhaps you can mix some sort of filler paste to the right colors .
Make sure you use a glue that is as dark as the wood .
The rest is care and patience .
Here's a repair I made after a stupid mistake .
Fortunately I had most of the pieces .
My glue was a bit dark ..
Rick
