Class A sheathed smokebox.

Hi there,
Can anyone give an approximate time frame or year when different numbered Class A engines got the sheathing.

If the 1218 got the smokebox sheathed other than in excursion service in the 80’s, I think it would have been late in the 50’s.

I’d be interested to find out when the 1213, 1214 and 1217 got the treatment.
