Vintage Sign Painting Lettering Brushes Lot of 3

Description

Lot of 3 Vintage Sign Painting Lettering Brushes.  On these, I can't make out any lettering.  I can't really read any brand name on them.
Keep in mind these are very vintage/old and the lettering is worn off on most. The brushes themselves are in Very Good condition.  Soft Natural Hairs. These are from an estate of an old Sign Painter.
These are made from Natural Hairs.  I can't tell you what kind because I am not the artist.
All soft and pliable.
Condition is Used but in excellent condition.  I try to show you the handles as well as the hairs themselves.  The handles are well worn as they would be expected in that profession but the brush themselves are in just lovely condition.  The pictures are part of the description.
They were well cared for by this ole sign painter.
