Anyone know of Lindorf pianos??

[perfect5]

I recently talked to a new student who has a Lindorf grand piano.  I've never heard of this brand,  and she is curious to know more about it, as am I.  She says it has been in her family, and she thinks it came from Europe with a relative.  I have been unable to locate any reference to Lindorf pianos and wonder if anyone knows anything about them - i.e. when and where they were made, etc.  The piano has been rebuilt, and I have not yet had a chance to look inside and see if there is any stamp or other information.  

Thanks for any info!
