I've collected some great techniques and resources for researching padlock history, and felt it was time to share them with you. Thanks to Paracentric for suggesting this topic. In this video, I show you how to use several sites and techniques for locating some great padlock info, and free downloads of catalogs and ads as old as the late 1800's

Dropped in at the local flea market and found a seller with FOUR bins of padlocks. Made some great finds, and future picks for my channel. Then, I go ahead and pick a Sargent that was in my purchase.")

Got this one from Mur-Lock 68. Standard Sclage KIK cylinder. No special pins, which makes it trickier to pick - no feedback from spools or serrations.")

As promised, here is a guide to my sites and tricks for shopping and estimating safe prices for your antique lock purchases. Links are found in the video (sometimes YT does not like descriptions with links). From the section on tips to avoid bad purchases.Look for these red flags:
* Shutter opens on its own (no spring)
* Bulging or Misshaped Pins
* Holes in the face (vs hole for Clevis)
* Badly Matched Seams
* Mismatched Key Style (warded key on push lock, etc)
* Highly Polished (often to hide rusty internals)
* Shackle Misshapen
* High Priced, claiming RailRoad, but no RR letter markings
* Partway Open, never shown closed
* No Bitting on Key, Decorative Only
* Gold Plates Claiming Famed Origin")

Got this in a bulk purchase, and could not resist the urge to rescue it from the rust. This is a double sided wafer lock, which uses a two sided key. After the cleanup, I do a quick pick.")
