Not an expert so can't help on value, but more detailed pics/descriptions as well as bore condition will be needed for the more knowledgeable members here to offer advice.  Sporterized rifles do not command the prices of unmolested examples, but are still fun to shoot, thus bore condition is an issue.

The top Krag, (#32,XXX), appears to have once been a model 1896 carbine.

Regrettably, a 1903 Springfield 'banded' front-sight was fitted to the barrel and the barrel-band had the sight-protector 'ears' removed. A 1902 Rifle rear-sight has replaced the 1896 sight.

The altered stock has the shorter lightening-cuts ('finger-grooves') of a carbine stock. There may be a lighter colored area of wood, where the 'sling-bar' recess was filled with a patch.

I think your Krags show pretty typical alterations and styling done by local Gunsmiths (and talented amateurs) of the 1920s and 1930s. The military stock was recycled to keep costs low. (The DCM was selling off Krags for $1.50 in the late 1920s)!

Your Redfield #102K, 'no-drill' receiver sight, was inexpensive, "back in the day". (Now they are worth about $80 to $100, if you need one). No 'metal work' was done to your Krags, except, shortening the model 1892 barrel and fitting 1903 Springfield 'banded' front-sights.

Most of the effort went into modifying the stocks (and the workmanship is way above "Bubba"). This kind of work on Krags had to be the 'Bread and Butter' for local Gunsmiths during the depression. Costs were kept down and utilitarian.

Commercial Hunting rifles were expensive. Custom rifles, built by firms like Griffith & Howe, using Krags and 1903 Springfields, were very expensive and obvious. They show fine metal work, finish, and amazing hand-crafted stocks.

We all wish our sporters were worth more. But when you hear news reports about military grade weapons you can think to yourself  "I have a couple of those!"
Gun shows were mentioned earlier in this thread, has anyone seen Ruger #3s in 30/40 recently, if so what do they go for? I saw one 35 years ago and they were asking $150.00, I wanted it back then but was as poor as a church mouse.

Thanks,

Did not realize there was much difference between the #1 and #3.
If these common sporters were expensive, we would not feel as free to use them or be able to cannibalize one to put a collectors item back in shape.
I saw a couple of ads for original Gatlin guns, if Krags were priced like that, we would be afraid to work the action to see how smooth it is, and they would all be behind glass.

Looked it up there are more differences than I expected between the #1 and #3. Evidently there were some 30/40s produced in #1, apparently not available now.

I had a #1 Varmit in .25-06. It killed a lot of whitetails. Really nice firearm.
