small Chubb dual control lock

[Gary Stephenson]

I like collecting dual control locks, especially the ones where two keys operate through a single keyhole. Most of the ones I come across are quite large locks, but had to open this one recently for a bank that was closing down and wanted some old safes opened to check they were empty before disposal. This was on a Chubb record protection cabinet and I have not seen this lock before in dual control guise. I had to drill it as I didn't have any picks to fit, but managed to get it open without too much damage to anything except the lock cap, nice little lock design.
