The Santa Cruz Eagle soda works bottle is a 4 piece mold bottle. I have had a few in the last 40 years. I think they are rated very scarce. They sell for between 100 and 200 dollars depending on condition, and color. There were quite a few soda works in Santa Cruz in the 90's, along with the pumpkin seed flasks. If you are interested in the S. C. bottles, let me know, I have a few available.
The age is mid to late 1890's.
