I wasn't sure where to put this question, but the paint on it might provide a clue, so I put it here. If it needs to be moved I understand. So the 5-20 I got today has a large bow bar on it. It's a deep red in color under a silver topcoat. I don't think the silver is original, but who knows. The writing on the bar includes the number "69" stamped on one side at the end that engages the saw. I'm not 100% that there isn't more to the "69", as it fades into the metal. Also stamped into the metal on the top of the other end is "Patent Pending". That's followed by thick rounded raised letters (not stamped in) that say "HARD SURFACED" in a slight arc. You can make out part of that in the pic below. The chain is an original Homelite, but that doesn't say anything. I know Homelite made these Limbing bars, but don't know if they were red, or if they used the term "HARD SURFACED" on them. If anyone has seen one of these and knows who manufactured it...........I'd love to know. It's in really good shape..........the silver topcoat did a great job of keeping it rust free!
