I got a response from Frank at tube ampology:
"Hi,
The current 4003 bezels will fit into 4001 Chrome surrounds.That is why to 4001 series has been discontinued.
I do still make the 4001V63C64 bezels, but they are machined in very limited quantities.
Thanks
Frank"
So I guess I can order the 4003 for my 4001
