The pins the OP posted appear to have a zerk fitting on the bottom. My guess is custom made. Stock pins could probably be drilled and threaded for a zerk fitting if you had a good machinist friend.
The doorman part number listed several times above is for hinge pins that have a grease zirk. It replaces the stock style pin and bushing with a pin that's been drilled and tapped and has provisions for a grease zirk. Definitely not custom, available through nearly any parts store in North America. I got mine off of Amazon.com for less than 20 bucks a door.
Trust me I just installed them yesterday
