Just for the sake of discussion...
R.J.R. has it spot on, the Boer War brought out the so-called 'Wrist Watch' and it was embraced for its quality and durability by the Officer Staff, so therefore it falls under the 'Victorian Era' for our usage, m/l. OK, as others have pointed out, it wouldn't have seen much use for Cowpokes since they ran on 'Cow Time', but we all don't pretend to be Cowpokes, there are lots of R.R. Agents, clerks, bankers, etc., that would have had the wherewithal to acquire one if it became available, so it can be considered acceptable if verifiable for each personnaes location, etc.
Now, as far as the 'volt' timeline goes, during the recent decade-long incursion into Iraq, the museums housing myriads of items well-known to the scientific community but little-known to anyone else, suffered multiple disasters and blatant theft. American troops were considered the best to track down and relegate the artifacts back to the original museums over time, alas, many are lost forever, but one jar with a copper tube and wire was found and returned for awhile, its present location may be unknown. The jar with a lid that had a copper wire and was said to have contained a vinegar solution was determined to be, in fact, a 'battery' of some early form, what it 'powered' or served is probably lost to history except for interpretation. Suffice it to say, 'Voltaic' is a more modern interpretation, or scientific stumbling' as it were, onto a historical endeavor used in the 'cradle of civilization' as most historians call that part of the world we are now so deeply involved in.
Now, as far as the song goes, these are the lyrics my class sang in post-WWII Elementary Schools, the song was in all our music books, they contained popular songs from Allies around the world, obviously pre-Cold War.
The Volga Boatmans Song
(phonetically spelled)
Yo-oo, heave ho, yo-oo heave ho,
bend your shoulders to the line.
Yo-oo, heave ho, yo-oo heave ho,
bend your shoulders to the line.
Ai-dada-aidah, aidadda-aidah, bend your shoulders to the line!"
Best regards and good researching!

P.S. Finally back on-line and in my digs after a 4-day respite due to the ice storms and power lines down all around me. It was actually kinda fun in a Cowboy way, after all a 'Country Boy can survive', but my wifey wussed out after the first night and went into Mom's, couldn't take the cold like she used to. I held down the Fort, just like the old days when we had Winter Rendezvous, only went in to town when the 'potable supplies' ran out. Restocked, warm and ready for the next storm this weekend! I pity the poor folks who may be down for another week, the Power Dudes need all our prayers folks, lost one here locally on a highline when the bucket broke and he dropped 80'. Many of the cross country power towers dropped due to icing, 30-40 miles in one place, and it will be awhile till some of our Pards are back.
