Interesting information and links. While my examples below are not of any high values, I find them interesting as they do conflict with the catalog listings, as they are later dated meters (1935) that are after the LKU dates shown:
L.F. Rothchild & Co. (Catalog references EKU as 11/23/1935):

R.W. Pressprich & Co. (Catalog references LKU as 09/12/1934):

Holcomb Crucible Steel (Catalog references LKU as 04/06/1933):

State of New York (Catalog references LKU as 11/01/1934):

This one is even more questionable, as a meter number of 511 isn't even shown in the above catalog
(Edit: Or might this be Meter 511 shown on page 310, attributed to 16th Floor of 11 Wall St.?) with usage from 06/22/1934 to 07/03/1935. I question if that is correct or not, because the central portion of the indicia shown below does not match the examples referred to in the catalog:
