The first thing is a horn that I haven't seen before. I looks just like the conical black japanned horn with the gold stripe that are somewhat common, but this one is much larger and has two gold stripes. Is it for recording? Has anyone seen one like it before?

I was also curious about this crank. Does anyone know what machine it is from?

Last, I haven't seen this style of cylinder before. They are brown wax, (obviously) but I can't find any info on the maker. There isn't any brand on them. The rims are not flat, they are slanted. The pictures don't show this very well, but they are sloped quite a bit. The number and song titles are scratched into the slant of the rim.

For example, the middle cylinder has the following scratched into the rim:
A014 Aint She Sweet
Here is a close up. Note the smooth inside and plain box.

Does anyone know anything about these things?
