I can create any inlay that you require, I can do this by either replicating something that is existing or if you have a specific design in mind and have a hard copy I can work from.
To reinstate missing brass inlay is not impossible, but it can however be difficult to achieve. If this is the case, I would advise to re-veneer & re-brass inlay the affected area.
Lifting and missing veneers can be repaired/replaced with as near match as possible.
I have a vast selection of old veneers that I have collected over the last 20 years or so.
