Larry -
Yes, I have an Excel Spreadsheet of the bows with major details and values. I also have insurance which allows me to get a good night's sleep.
I have most bows categorized as follows...
1 - Manufacturer, e.g., Bear
2 - Model e.g., Kodiak
3 - Year, Chronologically, e.g., 1959
4 - Length, e.g., 56", 60", or 64"
5 - Riser Characteristics, e.g., Sight Windows, Maple, Purple Heart, Rosewood, Bubinga, Wedge, Long, Short, etc.
6 - Serial Number, Draw Weight
7 - Unusual Feature or Notation, e.g., Factory Compass in grip, etc., original owner or other historical data.
8 - Price I paid, or value
Almost an impossible task to keep up with as bows come in and go out.
