Vintage Shogun Frame and fork CR MO 400 Mixte with Tange Champion 5

Solid but some surface type rust here and there. No dents or damages except on the very bottom where a kick stand once was bolted it looks like someone may have hammered that area a bit to maybe allow the stand to nest up in there?  the steer tube of the fork is stamped tange and there is an 83 there also which might indicate the year? the Tange Champion number 5 sticker has taken substantial abuse also note the made in Japan sticker at the bottom of the seat tube.  the old school size measurement from the center of crank to top of the seat stay is 22" or 55.8 cm which I would consider to be a large.
