Hi,

I have retrieved the pics I was looking for.
They are from a Levasseur prop which had been "redrilled". If it was not "damaged", it is very unlikely anybody would suspect anything special: the last pic is the other side of the hub and except a very thin glue line, nothing is visible. It was an airworthy modification as you could see the military stamps.
There are dowels in the old holes, but I do think if it possible to see them from a facial and lateral X-rays because the dowels are probably made with a denser wood and, anyway, there is to be a peripherical compression of the wood, so denser "tubes" which will appear as whiter lines (side view) and whiter circles (facial view).
On the Levasseur there is also a space between the wood disc and the hub which have to appear on a X-ray.
On your prop, the added wood disc seems (if it is there!) thicker than the one of this Levasseur.

Let us view the scans when you will have made them!

Regards,
PM
