Erfurt was not making Gewehr 98s after 1908, only assembling them from sub contracted parts in small batches (star rifles).
My guess would be a Kar 98. Erfurt was the primary producer of the Kar98 from 1908 to 1918 and at it's height was putting out close to 1000 carbines a day (almost a carbine every minute!). Some Erfurt serials show double suffix blocks to indicate this high level of output.
Is she in full military ? Sporter ? Be careful with the U.S. import laws, that carbine would have to be de-registered in the U.S. and pre-registered up here in Canada which apparently is a costly and timely pursuit and only after you find someone in the U.S. willing to deal with you and an importer in Canada with the licenses for import.
The caliber, if it hasn't been turned into a sporter, would be 7.92x57mm Mauser.
As others have mentioned, pics would be great

If you have no pictures, do you notice any similarities between these examples these types of markings ?
