Thanks guys
I bought the walnut veneer from Oakwood Veneer which has become my new go-to place after Mr. Widget recommended them years ago.
I do have the original 4338 grilles. They are to the side in the photo above.
The baffles are indeed blue as per the formula Bo provided for us years ago.
They are too heavy and I am not looking forward to all the weight they will gain with the addition of the components.
I think that you will like them.
A lot!
