IMSLP Forums

Apologies if this is the wrong forum to ask this question: I am looking for the violin sheet music for the following pieces that are not posted on IMSLP and not for sale on Shar, Hal Leonard, or Sheet Music Plus: Mamedov - Symphonic Variations for Violin and Orchestra Arvids Zilinskis: Violin Concer...

I'm looking for the violin part for William Kroll's "Banjo and Fiddle" (1945) and was surprised to find *none* of Kroll's compositions available on IMSLP. Can anyone help? TIA.
