I just recently got this camera and I have not seen anything similar my best guess is it’s a Houghton ensign camera, my best guess is the 3 1/4 box camera. Unfortunately the where camera logo would be at the front is missing. Also I am unable to know what the serial number is because there are aroun...

I am not sure if when it was manufactured is correct because there are no advertisements for the company or anything relating around in the mid 1910s and onwards

I recently got this camera it has seen better days, but I got it because I have never seen one before. My best bet is that it is from T Eaton. ( A Canadian department store chain, which around in the 1910s started to make a few of there own cameras and named then “Teco”) I am not fully sure because ...

There was a no.1 Teco folding camera up to at least a no.6 Teco folding camera

This camera was made by the Canadian camera company. I could not find anything about it beside one advertisement This advertisement came from vol.XII of the Canadian druggist in April 1900. The bullar camera takes 3 1/2 by 3 1/2 film.

The only other information I found shows Seneca may have made a Seneca snap before but the site never shows when it was manufactured http://camera-wiki.org/wiki/Seneca_Snap

I bought this camera a few weeks ago and the listing said it was a Seneca Snap 2A. I can confirm it says Seneca Snap by the strap. But I could not find much information about the camera, it has one exposure setting, just a set time and the back half is made of cardboard.

The camera came in 3 colours at least from what I know black, blue and red.
