The starter set I gathered from around the house.
My first quality practice cylinders.
American Lock 1100 series in 5 pin and 6 pin cores.
Abus No. 34/55's 6 pin cores. (These are the NYCHA surplus ones from ebay. I bought them to put into service and try picking later so I asked for additional pins to match the keying of one of the locks. Instead the kind seller gave me 4 extra keyed alike cores + keys.)
Summer sale pack from macgng that just arrived today.
