Thank you Andre. I’m late reading this, but your knowledge is impressive. I have a taxiphote, and have measured the slides as being 18cm x 9 cm. Is that essentailly the same as the 17×8.5 you mentioned?
Hi Tony,
8x19cm is a different format and as far as I know there is no Taxiphote that supports this format. 8,5x17cm, 45x107mm and 6x13cm were the most common stereoview formats early 20th century but there were many more, like: 9x12cm, 9x14cm and 10x15cm.
Regards,
André
That’s interesting. Perhaps my device is not a true taxiphote, but it is a desktop, chain driven viewer, and that is the size of the slides inside. Unless the measurements are made of the images, not the pieces of glass. Is that the protocol?
Hi Tony,
The type of viewer is determined by the mechanism, not by the format of the glass slides or stereocards. Most viewers were available for different formats. You read more about the different types here: https://stereosite.com/collecting/a-multiview-stereoscope-comparison/
