Echtes Leder Leather jacket

Vintage motorcycle leather jacket in good condition. The tag says size 102, but I don't know what kind of sizing is that, maybe the chest size or something (see exact measurements below). The jacket is in good shape, except some minor surface creases on the leather, mostly on shoulders and sleeves (white leather), which can be seen on the photos. The jacket is old and heavily used so it's normal. All zippers work perfectly fine and there are no holes on the pockets. The inner lining looks good except one smaller tear above the inner pocket which was fixed by sewing (pics upon request). There is also one button missing from the collar and the leather lace which is used for hanging the jacket is ripped. Other than that everything is in very good condition.

Measurements are following and also can be seen on the photos:

Pit to pit - 56 cm (22 inches)
Shoulder to shoulder - 44 cm (17 inches)
Waist - 46 cm (18 inches)
Collar to bottom of the jacket across back - 65 cm (25.5 inches)
Sleeves - 64 cm (25 inches)
