What’s up with Boehm flute concerto ?

Hey so I’m looking for audition repertoire and I am in love with theobald boehms grand polonaise, I worked on it before, however I have seen an standard repertoire lists that his concerto in G major is also a good piece. The slight issue is I have seen the music available to purchase on a couple of sites however I can’t find any pdfs or recordings of this piece online? Is it not a very common piece? I was thinking it would be fun to learn but I can’t find much information on it anywhere and I’m second guessing the strength of it for being used in an audition…
