Hi!
Our esteemed organizer, Bill NY, put a good posting about the Southco E3-35-35 over at http://barthmobile.com/eve/for...201059223#4201059223

Another website, http://www.ssint.sg/UserFiles/...Large%20size_1a.pdf, shows this and comparable form-factor equivalents.

E3-36-35 is the 8mm Hex Recess
E3-35-35 is the Southco Tubular Key (uses key E3-5-15)
E3-34-35 is the 7mm Square (uses key E3-4-1)
E3-33-35 is the 7mm Triangle (uses key E3-3-1)
E3-32-35 is the 3mm Double Bitted (uses key E3-2-1)

A few google searches for those part numbers led me to some potential vendors:

I am going to order some for me. Prices aren't quoted, they are inviting requests for quotes. Do you need any too, that we could bundle in on a quote perhaps?

best regards,
Matt
