I just today picked up an example of this model; what a beauty!
I used to think the K5 was their nicest steamer, but now I'm not so sure...
It's been my understanding that Gilbert stamped the inside of their boilers with a date; I cannot find such a stamp. It has the (2) brass "buttons", which I guess means a 1946 build...(?)
It's such a joy to work on something this basic; a few screws, a 1/4" nut driver and that's all it takes.
It runs very nicely: smooth and quiet, except:
3 of the 4 flanged drivers have loose tires: what is the recommended glue for securing these?
As always, thank you in advance.
