Help Identify BMW Wheels

[Bushwhackersam]

Does anyone recognize these wheels? Curious what style they are, and trying to get some info on them, such as size, offset, width, etc. Hoping they'll fit on my e36 M3. I looked on both http://felgenkatalog.auto-treff.com/ and http://www.bmwstylewheels.com/ and came up empty. The stamping makes me think these are factory wheels, but I can't get a good look at them. Hoping someone here might have some info. The seller called them M-Pars, but these are not M-Pars. I don't know what they are or what they came on, but I really like them, and want to find a set. Any help would be appreciated.

Pretty sure they're Breyton Inspirations.
