But I'd recommend cruising eBay and look at similar knives in similar condition, and look at how much they sold for.
If it's marked "Schrade +", then it's stainless. For that time period it would have been 440A.

As a registered user, you can post pictures using a picture hosting site. I use Imgur, but there are others. Once you have uploaded a picture to the hosting site, copy the web address of the picture. Note: picture web addresses must end in .jpg or .gif
Then go to your post and click the image tool on the toolbar next to the smiley tool. Click the link icon in the popup. (Looks like a chain.) Paste the picture address into the window. Then click the INSERT button.
