In finding and looking at this forum it seems like a good place to start.I have seen some recommend something called The Lock Collector.Hi, I had an old key from when I was a kid and inhereted one from my dad. I never thought of it as a collection until recently; since antique keys have caught my interest, mostly larger keys or those with very interesting looking bits. Needless to say, over the years I have acquired a mass of more modern keys.It seems to be a magazine, paper or e-magazine I cannot determine. Perhaps someone can help with a where to look if I do not find it first.
The ancient Romans came up with metal pin-tumbler locks, using keys of bronze, iron, or precious metals.
The information on this website will, however, usually produce a reliable manufacturing date range for a majority of American utilitarian bottles manufactured from the early 1800s to the mid-20th century.
Using physical, manufacturing related diagnostic features, most utilitarian bottles can usually only be accurately placed within a date range of 10-15 years (i.e., 1870-1880 or 1885) . Like many industries making the leap from manual craftsman production to industrialization and automation, technological advances in bottle manufacturing were not immediately accepted by glass manufacturers or their workers.
A substantial amount of bottle type specific information must be reviewed by a user to increase the probability of dating accuracy.
Additional reference materials outside of this website must often be consulted to narrow down the date of any item as far as is possible and to really get a "feel" for the history of the bottle in question.
This bottle dating "key" is a relatively simple "first cut" on the dating of a bottle.
