Show Off Your Bakelite Beauties! Anything Bakelite!!

Nice all! Keep'em coming. Quite a sub-culture of cameras.
 
and now for something completely different...

Just after a new cell had been made and fitted. Being 80 years younger the meter now shows for f/16 and 400ASA film.

I like that David. Never seen one. Never knew they made one. Nice! (Researching 23° Scheiner) :cool:

Scheiner

The Scheinergrade (Sch.) system was devised by the German astronomer Julius Scheiner (1858–1913) in 1894 originally as a method of comparing the speeds of plates used for astronomical photography. Scheiner's system rated the speed of a plate by the least exposure to produce a visible darkening upon development. Speed was expressed in degrees Scheiner, originally ranging from 1° Sch. to 20° Sch., where an increment of 19° Sch. corresponded to a hundredfold increase in sensitivity, which meant that an increment of 3° Sch. came close to a doubling of sensitivity.[5][7]
100 19 3 = 2.06914... ≈ 2 {\displaystyle {\sqrt[{19}]{100}}^{3}=2.06914...\approx 2}

The system was later extended to cover larger ranges and some of its practical shortcomings were addressed by the Austrian scientist Josef Maria Eder (1855–1944)[1] and Flemish-born botanist Walter Hecht [de] (1896–1960), (who, in 1919/1920, jointly developed their Eder–Hecht neutral wedge sensitometer measuring emulsion speeds in Eder–Hecht grades). Still, it remained difficult for manufacturers to reliably determine film speeds, often only by comparing with competing products,[1] so that an increasing number of modified semi-Scheiner-based systems started to spread, which no longer followed Scheiner's original procedures and thereby defeated the idea of comparability.[1][8]

Scheiner's system was eventually abandoned in Germany, when the standardized DIN system was introduced in 1934. In various forms, it continued to be in widespread use in other countries for some time.

Thanks; in a nutshell, it's a modified Weston 650 and that appeared in 1937 with the Leica version appearing in 1938.

Trying to nail down film speeds is one of the black arts. There were so many changes and politics came into it when standardising things. There were some interesting fights in the 30's about film speeds too with international get togethers resulting in a lot of bad feeling. And then in the 50's and 60's it started again...

The 30's are a real mess as films were seen as something vague like "fast" and no one really new what that meant. I've a box or two of old exposure gizmos and their instructions and so know the hard way. OTOH, assuming the sunny 16 rule works for midday in July I reckon that films in the 30's were about 8 to 15 ASA but that's based on charts and so on.

And there was this:-

Being a pedantic old git I felt the need to look up 'bakelite' to see if it was a generic term or specific to a certain material.

I found that it is also called "polyoxybenzylmethylenglycolanhydride" and decided I was out of my depth.

Anyway, thank you Mr Leo Baekeland.
 
Coronet%20Midget%201-XL.jpg


Coronet Midget in mottled brown Bakelite. Vintage 1930's. Kodak cassette to give an idea of the size of it. TTH made the f/10 lens.

Overexposed to show the detail.

Regards, David

Oh wow, I've heard about the Midget but never seen one before. I had a coronet deluxe box camera in the past. What film did it use to take?

16mm on a tiny little metal spool just like a (say) 127 or 120 spool only a lot smaller. It took 6 shots.

I had one when a tiny lad in blue with the blue case etc and used it until I sold it for a few shillings towards a Kodak folder.

Now look up the price they want for a blue one on ebay...

I think I have a Spartus in the basement! Gift from my sister from a yard sale. I'll have to dig it out.
 
The Worlds Most Popular 35mm Camera (for 1928 Anyway). The QRS Kamra. This marvel follows the Ellison in design. I’ve used this, and it’s actually a pretty good imagemaker. Format is 24x32 mm

Wow, that is quite unique. Amazed at all these camera variations.
