Webster had the first changer that could change records at all 3 speeds and for all 3 sizes - but using only one kind of record at a time. It looked very much like the 2-speed model they came out with the previous year, with a small box of toys included. But you had to be an expert at mechanical devices to use it. You had to take the turntable off to change the "slow" position on the speed knob to be either 33 or 45 by putting the little spring on the motor shaft or taking it off (at least they provided a little stud to store it on). Then you turned the rest post to set the record size, either for 7", or for 10" and 12" records. In the 7" position, the pickup arm's rest position was closer to the spindle, so the auto shutoff didn't work and the changer repeated the last record (7" records were not heavy enough to work the spindle-weight auto shutoff anyway). If you were playing a 7" record, you had to clip an extension onto the nodding shelf (in the 10" position) so it could reach a 7" record. Otherwise, you rotated the shelf for 10" or 12" records. If a large-hole 45 was used, an adaptor ring (called a "spider") had to be snapped into the hole so the regular spindle could drop it. And the 7" shelf extension had to be adjusted for the different thicknesses of 7" 33 and 7" 45 records.
The second production run of 356 had a 3-speed drive for the turntable, so it was no longer necessary to take off the turntable to change speed. A second-run Webster 356 is shown above, set up for 7" 45.
