Need help identifying a shower valve

[Erik80]

Trying to identify a shower valve from a 23 year old home in West Vancouver. The trim is branded Delta Select, but the valve does not match anything I have seen, and I've spent hours looking on the web, as well as consulting local plumbing shops. The rough in valve does not appear to be Delta, as it uses a plate and four screws to secure and seal and seal the cartridge to the rough-in, rather than a large nut. Any guidance would be greatly appreciated. Thank you!

Most valve parts are still available. Trim parts are more difficult to find.
