frame -

same frame also used to build cycles sold as motobecane, orly, astra, dynamax as well as a department store chain badge here in the u.s. there are likely other badges also which are not known to me.

saddle -

never saw one like this before. is heel plate marked with a date? my guess would be that blue lacquer is aftermarket, but only a guess.

sounds like you are having no end of fun with this project, as with the others you have shared with the forum previously! thank you for letting us in on it.
