To be honest...a LOT that I have learned was from books by various authors...and help from folks on websites like Tom Jacomet...and his website
At the same time...I've been a sleuth
over the last few years when it comes to either finding info on the 'Net...or having the "mind-set" to think about things / situations...and try to "piece things together".
This is an EXCELLENT example of that.
As a teenager in highschool...I always read about archeology...and was amazed at the discoveries that were constantly found.
I guess that I have applied that "train of investigative thought" while working with my collectible lures & items.
Thank you for the VERY kind words
