1940s Lace-up Shirt with Gusset, REGENT / Western Rodeo

This is a 1940s REGENT lace-up shirt with gussets (photo 3).

The original laces are missing, so please customize them with leather or cotton laces to your preference.
The second button from the cuff on both sleeves is also missing (photo 7).
*I wore it layered with thermals without the laces, so I cannot provide replacements.
It has a level of wear that would not be noticeable to someone who understands vintage items, and it can be easily repaired or customized.

There is no size tag, so these are amateur measurements. Please consider the flat lay measurements.
I believe it fits like a Japanese M to L.
Shoulder width: 42 cm, Body width: 53 cm, Length: 72 cm, Sleeve length: 59 cm

Thank you for considering.
I plan to ship via Yamato Transport's Takkyubin Compact or Takkyubin.
Due to work, shipping may occur on weekends, but I will ship as quickly as possible.
