Example SUS scores / proof of outcome?

I'm currently investigating the probability of introducing System Usability Scale (SUS) as a means of quantifying the comparison of new vs. old systems. The system in-question is like-for-like, and as such SUS appears to be an ideal means of gathering such user satisfaction ratings.

However, to get buy in from the wider project team I've been asked to validate my proposal, which is where I become stuck.

My immediate thought being to pull together a list of organisation names that employ SUS as part of their processes. Not necessarily the actual data, but a means of demonstrating that organisations of all shapes and sizes have used (and indeed make use of) SUS for the purpose of validation among other things.

The fact that SUS has been around for 30+ years requires justification on my part I'm afraid. And whilst I appreciate similar questions have been asked in the past, I've Googled aplenty but unable to pull anything of relevance against what I'm ideally looking for.

If anybody could point me in any kind of direction it would be highly appreciated.
