As an old hippy I always found greasers to be a bit intimidating, but I have to say, these three seem ok.
The brass one is 1 3/4" across the top. I didn't take the lid off because last time I did that it was a bit of a job to get it back on again. In the end I put the greaser in the vice to make it perfectly round and then the lid went on easily.
The two small ones do have some inscription on the lids - not clear what it is I'm afraid.
