I haven't heard of Montrose variety, and don't know any apricot varieties except what grows here in Ladakh. There are two locally named and grafted varieties here, that have edible kernel and good fruit. One is the tastiest fruit, especially when dried, needs no extra sugar in jam, and has a distinctively wrinkled top. The other has a white seed shell (the only one locally with that), sticky sweet fruit, and a distinctively blocky shape and slightly pale color.
The winter is cold here at 10,500 feet, but just a little higher up in this region apricots no longer ripen properly. Even at my altitude, they don't get as big or as sweet as down at balmy 9000 feet, lower down the Indus River in our region. My understanding is that apricots like summers with intense sun and dry air and dry weather (we irrigate at ground level here). That might be more of a problem than the winter minimum temperature.
I'm sorry, that won't help you with your search for Montrose.
