Both of these cameras were likely introduced in 1935. Oringinally, both cameras had the shutter release directly on the shutter; the shutter-release was later moved to the body of the camera.
According to a 1939 Welta catalog, the Symbol was available with an f/6.3 Weltar lens and either a Vario shutter or a Prontor II shutter and sold for 33 and 40.50 Reichsmarks respectively.
The 1939 Catalog states the following about the Trio (translated from German):
Photography, inexpensively, with the Trio.
Do you like? You know that a radio receiver with 6 tubes sounds better than one with 2 tubes. You have to expect such differences in the camera industry. If you’re looking for an affordable 6x9 camera with good optics, then the Trio is what you’re looking for. You need to know that the trio has an f/3.8 lens, a compur with self-timer and a shutter release on the body of the camera. A very inexpensive 6 x 9 camera.
The trio is a dual format camera, either eight exposures recorded at 6 x 9 or sixteen of the image size 4.5 x 6 cm. The lenses are three-element f/4.5 Trioplan or f/3.8 Trinar. Or there is the 4-element Tessar lens.
