Very true!
I have come to a few conclusions, to wit:
1. Your tail is slightly stubbier, and the logo is not as detailed.
2. My tail is longer and the logo is more refined.
This would mean that my JB is probably produced later than yours.
3. John Barber was in production from 1810-1834 per Lummus.
4. Reference this page:

It would suggest that your razor was produced towards the early part of the date range.
The aforementioned thread would suggest that my razor was made past 1825ish and almost certainly towards the end of Barber's business, 1834.
So, that's my reasoning anyway. Whatcha think?
