Chubb 4L66

[Blackjack]

Hi Guys just found this fantastic site, don't know where i've been too have missed it?
Doe's anyone have any info on the Chubb 4L66? I have just got hold of a few of these all in there original boxes including leaflets and fitting instructions.
All I know is that it is the predecessor to the 4L67 guardian, is not BS approved but doe's use a slightly smaller version of the current AVA cylinder. Apart from that I'm stuffed.

I think the AVA cylinder is the same size / design, but the keys are different lengths ?

The cylinder does appear to be of the same size however it fixes through the backplate via 3 screws, whereas the current 4L67 only has 2 fixing screws. It does have a rather strange internal unlocking knob, hopefully I wil get some pics to post soon as I have never seen this lock before.
