A couple generic observations. M1919 Savages were neat guns, interesting to play with, worthy of addition to a collection or for general shooting. Built initially to capitalize on the burgeoning sport of military-style smallbore match shooting that was all the rage at the time. Most serious shooters and gun writers at the time relegated it to 2nd-tier status behind the likes of the Winchester 52, Martini, etc. Reasons usually given: too light in overall weight for serious target work, slow lock time, indifferent triggers, too light barrels easily effected by the unnecessary full length wood stock, poor factory sights. Said traits confirmed by my own experience with one long ago, and why I've pretty much ignored them since. Later iterations of the M19 fixed most of those concerns and are generally a much better target arm.
Be very careful when cleaning it. If the chamber/throat is damaged/worn by sloppy cleaning rod application there's no hope of re-barreling it. The receivers/barrels were one piece construction. (Why Savage did that with the M19 and others is something I've never been able to figure out. Not one of their better ideas, IMO.)
If it's indeed a Lyman 438, treat it with kid gloves. They weren't the world's most rugged scope. For sure do not over-tighten the clamps screws - the threads in the pot metal which the mounts are made of will strip out quite easily.
