I have three (3) Frisco switch padlocks and one (1) key which opens all three locks. These were inherited from my father-in-law who was an engineer for the Frisco. All of the locks have a short piece of chain attached. They are all made by "Adlake". Two are marked "FRISCO" on the back. The third is marked "SLSFRR". The brass key is marked "FRISCO". I will take offers on the entire lot for the next week, after that if no reasonable offers, I will list on Ebay. Postage will be at cost. The total weight for shipping is 4 lb.
