Hello to the resident experts! This post is submitted with great respect for both the time you folks donate and to your years of accumulated experience. If any of you find this an interesting puzzle... beautiful. But I am in no way expecting or demanding your responses.

Background: My father purchased this bike from a neighbor during the 1960's in Wyoming. He repainted it a bronze color to cover the original purple. He rode it before and during college a moderate amount but from about 1970-present it has been in storage - protected from the elements but not from dust. Due to this it will likely need a fair bit of clean-up and re-tuning, but it has not been on the road at all since 1970.

I have been entirely unable to locate a serial number but I understand this is common for this generation of Peugeots.

Goal: Both he and I feel that it's time for the bike to find a happy home and we are hoping to determine a rough estimate of it's year or model and if possible a ball-park idea of a fair asking price? I'm including what I hope are detailed enough photos. Please let me know if any additional information or images would be helpful.

Again,
Thank you for any time or effort involved in advance!
