The pictures are from a family album dated 1948. I believe these are the same car - the "first family car". I'm having trouble finding other online pix to identify it - the "slant-back" or "fast-back" is different from many models that come up when I search. And I haven't been able to locate model "charts" for ID purposes. My friend who knows a lot about antique cars thinks its a '38 Oldsmobile, and if so, I can't find the series/model specifics or a good picture. It's also very similar to 1937-38 Plymouths, but again I can't tell for sure what year/series/model etc. Any ID help much appreciated! And what details helped with the ID so I can learn. And if you can provide any info about the trailer, that would be a bonus! (And please forgive any improper use of terms - I'm out of my knowledge area ) Thank you!
