Unknown Maker

This is an Alto Flugelhorn inTrompetenform in Eb, by an unknown maker. There are no markings on the instrument.
When it came to my home, the outside looked good, but the inside was very dirty. After cleaning, the instrument plays. Unfortunately there was no original mouthpiece and all my Alto Horn mouthpieces have a smaller shank than the receiver, except one that fits with a little plumbers tape. However there still are some very noticeable intonation issues.
