chrisorros Posted July 9, 2020 Report Share Posted July 9, 2020 Looks like an old style RKS for the 3g114 but never seen it in steel & the centre square is a 7g with is thinner than a normal RKS. Anyone seen one of these before? Quote Link to comment Share on other sites More sharing options...

grahamparker Posted July 9, 2020 Report Share Posted July 9, 2020 Didn't. Swapped the curtain a fitted a 3g114 lever pack as the customer had just taken over the premises so decided to change the internals. Quote Link to comment Share on other sites More sharing options...

Count Muppet Posted July 9, 2020 Report Share Posted July 9, 2020 With the end of the pin still being completely round and thicker than the flat part, I’d be tempted to try a normal key. its possible that the flat part is there to aid key cutting on an early machine? the Chubb key used on those old style I’m sure are the same shape all along Quote Link to comment Share on other sites More sharing options...

chrisorros Posted July 14, 2020 Author Report Share Posted July 14, 2020 Had the customer bring the lock in it's a chubb blue flash. From the early 60s. A disaster for chubb as they tried to save cost with plastic parts. They tried to save face saying it was meant for the South African Market. As it doesn't have a curtain you can use a standard blank as shown below. So in 20 to 30 years the next one comes in you'll now you can cut it on a normal 5g utility blank Quote Link to comment Share on other sites More sharing options...
Count Muppet Posted July 14, 2020 Report Share Posted July 14, 2020 On one hand you think that the lock is a pile of crap, but then you realise it’s lasted about 60 years so can’t be bad at all Quote Link to comment Share on other sites More sharing options...
