Ted -
Great find! Dusty Roberts was a historically prominent figure in archery back in the day.
The four heads to the right are all Bitzenbergers.
The two Case heads are common.
The sloped shoulder heads with convex edge look like Hovarter heads, but hard to tell for sure from the image, would have to see in person to positively identify.
The little traingular head I can not identify, but have had one for many years.
The two CBP small game heads at the bottom are nice heads.
The leaf shape is one I can not identify, but have had one for the over 30 years, but it has a bullet ferrule. LIke Dusty, it also came from California.
