toploaders

[f1builder]

i have 3 or 4 good toploaders but haven't been able to I.D. them. i want to put one in my 47 tudor sedan.

1. unstamped but was told it is a 39 but it don't say 78 on the casing.

2. 18 or I8-4335583

3. 18 or I8-6664769

i have a nice set of gears out of my old 41 ford that someone told me would fit the 39 box perfectly.

thanks for any help.....
