Watling 5c Overflow Push Lever Assembly

[jdohio5]

I just got a mid/late 1930's Watling 5c Rol-A-Top which was my grandfathers and I want to get it working. One thing I notice it is missing is the overflow push lever assembly. Does any one have one they would sell or know where i could get one or even be able to give me the dimensions of the parts so that I could make it myself? Any help would be greatly appreciated.

Thanks,

Jonathan
