From an estate, a 78 RPM 10" Record titled Duck Calls - for Mallards - by Philip S. Olt - 1951. Hard Rubber Game and Bird Calls. No manufacturer listed on label. Feels like it is made of Shellac. I played both sides and of course there is minor noise from age and use but I heard no skips. This relatively clean for this vintage of record on both sides but does have visible minor scratches and stains. The labels are pretty good. Generic white paper sleeve.
Thank you for your interest.
