The first (relatively) comprehensive arrangement of the tefillot, what we now call a siddur, was compiled by Rav Amram Gaon in Bavel a bit less than 1200 years ago. The nusach there is v’lameshumadim, and hence, it is difficult to call this nusach Ashkenazi in any way, whether it be Poland or German. So too in the siddur of Rav Sa’adyah Gaon. However, in the Sefardic (Spain, not Iraq) transcription of Siddur Rav Amram, it is already v’lamalshinim.
According to some scholars, these two words were once considered synonymous and both versions, as well as others, like v’laminim etc… were found in different siddurim, both Ashkenazic and Sefardic. Of course, as The Wolf pointed out, no standard ashkenazic siddur has v’lameshumadim anymore.
