When I see something interesting and like
to know more, I go to Safari and Google.
In the "search" option, I typed in for example,
"Hamilton Toy Wagons".
If no results, I type in another phrase like
"vintage toy wagons".
A page opens with information for various
items for wagons.
There's also another page listed as "Images".
I go there and scan the various photos of
wagons.
When I recognize the wagon that is similar to your photos,
I click on that site or "visit".
There I found all the Hamilton toy wagons
that have been sold, or are being offered
for sale and the history.
I also use the "search" option in this forum.
There's so much great information and images
in the CABE vaults from the past.
Much depends on the words you use
to get the results you desire.
Btw:
I found the second photo that you were asking
about on "eBay". There were various wagons to
bid or "Buy Now".
If I want more infornation, I will submit a question
to the buyer .
If the buyer has several wagons, then I feel
he knows about the item or can point you to
those that know more.
If the buyer only has one to sell and does not
provide much information then he doesn't know
what he's got or is giving out wrong information.
Many times I have seen a bike being offered
as original, when anyone that knows about
what an original should be knows that this
is not and gets upset.
I don't get upset. The buyer is ignorant or is
not on the level. In which case, I will pass on the
item. Good Luck !
