DPh:
Bell's Mannlicher Schoenauer exists today and is in the hands of a collector in the USA.
I have seen photos of it in an article by Don Henry in an American gun magazine,
it even has Bell's 3-digit Nairobi phone number under the trap in the butt!
Unfortunately I would be unable to locate the article in the short term.

You could contact Don, or the Mannlicher Collectors Association, directly with your enquiry.
Might be worth joining, or subscribing to their magazine. Contact details are on their web page:

Meanwhile, here's about the best photo I could find on the web at short notice:

Sorry 'bout the size, the image is stolen of course!
Note also that it has the 1951 safety, the original was a Mauser-style flag safety on the cocking-piece.

BTW, you can buy Denys Finch-Hatton's 6.5 MS if you've got a lazy $18,000 Australian lying around!
