Archaic/Proto Euryscope?

[cdholden]

#4 seems to be quite popular in this 2-3 year time frame.

#4 seems to be quite popular in this 2-3 year time frame.

While #3 will cover 8X10 nicely the #4 is really superb on 8X10 with lots of movement possible. I'll guess that's why they were so popular. I have one that someone took the time to put into a Size 3 Wollensak Studio shutter.

Another blank marked series IV - this time a size 5 covering 14x17" 23,159.
Listed as 250952846868. Very clean.
Focal length ("just under 20 inches" was checked with the lister. A lister who was delighted to be able to learn the relationship between focal length, aperture width and aperture value!

Another very early one:

22052 rim marked with III

I think it is worth mentioning that Petzvals in plain barrels, which look very much like early Euryskops, appear to be quite common within this time frame as opposed to earlier productions. They are without size engravings at the barrel edge.

It can be difficult to confirm whether the lenses are Euroskopes or Petzvals as the WHS central position is difficult to confirm in many photos. I think that "no edge size number engraving" means a Petzval in this serial number range.

I am able to add a considerable number of lenses to-day. They are taken from Corrado's book -page 130. The new lenses (from other sources, as well) are in bold.

Corrado give many more details of Euryscopes after serial number 24192 (dozens!), but they are not included here!

Unless there is a dramatic new source of these lenses, I will just edit this posting to avoiding "bumping"!

Just pulled the trigger on one of these pre-euryscops.

24473 marked 6. Complete with original flange and hood.
