I think you mean 1837, eh ?
But as you say, moot point since this was some photographic method to be used for just-this-purpose. And since there's no shortage of photography buffs out there, and no shortage of history on the history of photography in general, that : Someone should have something to say about this.
As far as donating it to a museum "on loan", be aware that not too many museums these days accept the terms of "on loan". Because there were horror stories of persons (or surviving family kin, etc...) barging into museums saying "give me back my item now". And then workers must stop everything they're doing, open cabinets, etc.... Or heaven forbid it was in storage somewhere and the museum or city can't find something that someone "loaned" 20 yrs. earlier. The lawyers get called, etc....
So most all museums now will only take donations. Not loans. Also the stipulation that some people used to try that : "Must be displayed". All such stipulations are avoided by museums, lest it turn into a situation where the general public is, in essence, dictating what will be the floor layout. As if the museum themselves can't make changes, decisions, etc....
It would have to be something over the top ridiculous to accept any constrictive terms like "on loan". Eg.: If you could prove that that was the wife of the founder of the richest mine gold strike in your district, or ....... you get the picture.
