The same tension roller assembly was used from 1928 to 1946.
Any camera from this era should have the part you need.
After careful measurement the tension shaft has a 5-40 thread.
A 5-40 machine nut can be subsituted for the snail. |

Speed Graphics through 1946 tension knob screws onto the tension shaft and the snail screws down against the knob to prevent it from turning. |
