American Cystoscope Makers Inc + Welch Allyn Sigmoidoscope Vintage Medical Set

I got this set of antique and vintage medical supplies from an estate sale years ago and I'm not 100% sure what everything even is. it all looks be in good cosmetic condition. i believe there is a variety of instruments in this set for proctology and Urology. The label inside shows from Feick Brothers. Feick Brothers Co. was a surgical instrument and medical supply manufacturer based in Pittsburgh, PA as early as the late 1800s. A think it is a really rare and unique collection. Please see all photos for more details and condition. Case measures 14.2" x 6.5" x 3
