Over the years Tollyboy have made a great many specials as well as the standard locks. They have mostly used 7 pin radial locks, there are an unknown number of 8 pin radial locks out there probably about 2 dozen, there are probably a few dozen change key variants they are higher than a standard lock. There are also a few custom made 13 pin radials, these have a double row of pins with cuts on the inside and out side of the key.
There are modified version of all the above locks, the modifications ranging from changing the pinning to modifying the lock to use trap pins. Modified locks look exactly the same as unmodified locks. I don't know how many trap pin locks there are but I believe more than 50.
There are 2 or 3 Van locks (these take an extremely odd key with pins in it pressing into holes in the lock), there are about half a dozen Medico these are almost twice the height of a standard lock and take different keys. There are the old padlocks of the original Hal Higginbottom design of which I know little and there is one Galaxy Lock from the Australian Lock Co. This is a serious horror show if you want to pick it, probably the most secure mechanical lock of all time. There is also one flat radial where the pins push outward at 90° to the direction of the key this is only about 6mm high.
There are also the permanent "locks" which only contain a one way roller clutch so they can only be screwed on there are about 20 of them sold.
I should have introduced myself earlier sorry about that I got distracted. Probably none of you know me, almost all of you know of me, probably some of you hate me. I am Tollyboy. I have been building these for half a life time.
