Vintage OK Brand (Ming Lun) Contractible bike

[dcbrown]

Hi folks. I am completely new to this. But I found this old bike today. The badge has what looks like Mt Fuji and says "OK MING LUN". The text in the side says "OK BRAND CONTRACTIBLE BIKE". I noticed "SHIMANO" on the shift lever. It is a complicated little thing and meaures 39" long and 29" to the top of the handlebar. Can anyone tell me what this odd little thing is? I cannot find a thing about it on the internet. Thanks for any help!

Neat. Looks like a bike made to be portable with quick adjust mechanisms to raise/lower handlebar/stem, seatpost and lengthen/shorten (virtual) top tube distance. Conceptually like a folding bike but "contracts". Just my guess. Based on Shimano lark ss rear derailleur Maybe early 1970s.

I think lun translates to "wheel" or similar.

Thank you. Are you familiar with the maker? I can't find a single thing about OK, OK MING LUN, etc. I am assuming Japanese?
