Vintage Yale Night Latch

[Onoff]

Anyone know the model number of this old Yale night latch?

 

 

 

 

 

 

Or where I might get one. Dates from the early 90s.

 

Cheers

Is that a Yale No. 1 Rim lock?

No2 is similar with different dimensions.

No, it's different. I seem to have got somewhere with it tonight. Cleaned but not yet greased. Not sure how the the triangle bit functions or if it's working right until I refit. Wondering what to re grease with, EP2, silicon grease etc?
