??? This week I thought I¡¯d take out the Leslie motor out of my 122 to give them a good cleaning and thorough oiling. Upon looking at the upper stack, I found an interesting slow motor ¨C the bearing had no port hole for oiling like the original motors. I am attaching a few pics in hope that someone in the group can enlighten me and others who may have one of these odd ball motors in their Leslie cabinet. I would be interested to know what company made these and at what time in the Leslie company history.
