According to Vienna's G2 report for 1913, The Montenegro Army had some 40 "heavy" guns available. It doesn't identify the type however. We do know they boldly fired down at the KuK anchorages at Cattarro with heavy ordnance. Again, the weapon systems aren't identified other than "schwere Geschützen". I always assumed they were either captured Ottoman pieces, or of French origin; now you've given cause to consider Ruski. ( Field / mountain ordnance was Krupp, but first line infantry carried Russian rifles.)
Montenegro has received from Russia as a gift along with other guns and 16 guns 42 Line Gun but I think exact model was 9 pdr steel heavy field gun mod. 1867 . or 42 line but 1867 model not 1877.

In the original document says Russia in 1909. donated to Montenegro 4 QF mountain guns 75 mm mod 1901 10 QF field guns 76,2 mm mod 1900 16 BL field moersers 150 mm mod 1870 (???) 4 BL siege howitzers 150 mm mod 1870 (???) 16 BL long field guns 106 mm mod 1870 (???)
I think this mod 1870 is an error in the document.
