I've actually seen most of these, so I can answer with 100% certainty. Unfortunately, you will not like the answer. None of the ones I've seen are widescreen, anamorphic or otherwise. One is open matte with as strong transfer and is the only one I can possibly recommend getting. It's also the only one that looked like it was transferred to video within the past 10 years.
Battle at Bloody Beach (1961) P&S
Mardi Gras (1958) P&S
Marines, Let’s Go! (1961) P&S
Three Brave Men (1957) P&S
Young Guns of Texas (1963) P&S
Life In the Balance, A (1955) Open matte with a high quality, recent transfer.
While I've never seen them, the others appear to be P&S with the possible exception of The Untamed, which might be non-anamorphic letterboxed.
The only difference between some of the P&S titles is that some have letterboxed opening credits and some have squished credits. Though the fact that they are P&S is so unpardonable, it really makes no difference.
