You will not find this information on the website. With a clearance date of 1997 you may not find much at all as some of the info may have been purged from the website.
The obvious question is why doesn't your company have a copy of your oiginal 510(k)?
Generally the only recourse is to go through a Freedom of Information request. This however costs a modest fee, but worse than that takes months, if not years to work through the process.
If this is indeed your 510(k) and you can prove it, perhaps the FDA could give you a non-redacted copy that is not subject to FOI. you would need to contact them to see if it would work.
Finally, perhaps its just the wording, but a special 510(k) is not a listing. It is a product submission, subject to review and clearance by CDRH.
Good luck.
