Oh wow, Old English huh? I have had the same bottle of that in my cupboard since the 90's. I never used it as I thought it was a stain. I will look at it closer again.
I will see if I can locate some Antiquax and see how it does.
I got it rebristled this afternoon, used up some of the scrap horsehair then started a new bundle of Chestnut horsehair.
Trimmed the bristles down and put the brushroll back in.
Got a handle from Menards for $3.
And if anybody is interested in the Domestic Vacuum Cleaner Co here is a list of patents that were issued to them
