Hello,
Your brown bottle has a couple of interesting features which could denote that it's quite old. Firstly, the lip appears to have been applied after the bottle was made. There are creases at the base of the neck, so called "stretch marks" from the maufacturing of it. I don't see any bubbles in the glass which is also a good indication of age of the earlier makes. Looks like an ealier porter bottle to me.
The vaseline bottle is very similar in shape to the old perfume and essence bottles I have, and they are fairly old, from late 1800's to early 1900's. The bottle is definitely an older type, the raised lettering, irregular bottom, bulging shoulder design, and just the look of the glass in general. If any of your bottles have stretch marks and bubbles, it's a good indication of an earlier made bottle.
Cheers Angela
