St. Louis, MO Precancel Identification Help Needed

Can anyone help me identify the correct precancel type for the St. Louis, MO precancel shown here?



If my measurements are correct:

13mm between bars
2mm high letters
3.5mm spacing between City/State name

Thanks.

Thought I'd bump this again for some help.

It does look as though it could be a Type 111, but the detailed PSS description suggests the lettering for that type is 2.5mm high. There is a Type 116 that suggests the lettering is 3mm high, but the 3.5mm spacing between City/State name appears closer together than in my example, but then again, I suppose my measurements could be slightly off.

What do you think?

PSS-111 sounds right - on the city coils the measurments can easily get mushed up some.
Very similar StLouis coils: PSS-111,PSS-116,PSS-L11

Based on the info available it appears to be type 111.
By matching the fact the 'M' is left of center of the 'L' above it.
A 116 would have the 'M' centered under the 'L'.

Thanks.

Very interesting comparison of these nearly identical looking precancels that have only very minor differences that are hard to notice without some knowledgeable information.

The left one is a 111, note the round "o's", the other 2 arw 116's. An L1-11 would be like the 111 but grey rather than black, and not easily read.
