MEDALLION Rugby Shirt Size M

Purchased at a select shop about 20 years ago.

This is a Made in England brand that supplies rugby shirts and other items to British public schools.

Worn only 1-2 times and then stored for a long period. I am selling it because I have no opportunity to wear it. There is no yellowing from storage, and the condition is quite good.
The color is white x bordeaux.

The dimensions are also shown with a measuring tape in the images, but:
Length: 78cm
Shoulder width: 50cm
Body width: 48cm
Sleeve length: 56cm

These are amateur measurements, so there may be slight errors.
It is roughly equivalent to a Japanese L size.
