10 looks like choke tubes for a Shot Gun ( are they marked full, mod
or improved?)


I asked the owner about text on it, here is the reply:

"The top third has the letters "Chr" on it - what I would call old school
writing loopy with the 'r' done the way the French would do it. The second
third looks like it has "lat" on it and the last third looks like 'Info' -
all a bit strange."

Also I should mention that these photos were sent in from England.
