I think those were made by Zabala Hermanos. Typical marks are *** = imp. cylinder and ****=modified. However, a gunsmith with a bore gauge should be able to give you a true answer in about 30 seconds.
# They relate to choke type, i.e., full, modified....
4 notches = cylinder choke (open), and one notch = full choke (tight)

1965 if it is an auto-5. There should be markings on barrel to indicate choke.
Browning Choke Markings "* " = full "*- " = improved modified "** " = modified "**-" = improved cylinder "**$" = skeet "***" = cylinder
http://www.guncustomizing.com/tech.htm#chokes There is no "conversion". The choke constriction is the choke constricition. What its called varies.
Depends on how choke markings on the weapon.
You will have to provide a detailed description of the action type, ALL markings, shell size, barrel length and choke, finish
Barrel marking include the proof marks, choke code and weight of the barrels. Please be specific and we can give a more direct answer.
Impossible to answer without a DETAILED description of ALL markings, barrel length, type of choke/choke tubes, stock material, engraving (if any) box, papers, accessories, finish, overall condition, etc..
