These are post-World War 2 British wool service shirts. They differ from the World War 2 variants because they are not pullovers. 

Many of these shirts are in used condition. Most shirts will have moth holes, but other than that, they all look to be in decent shape. With some work and care, these can be used for daily wear.

These are great for the fall weather as they are made of 100% wool and they will keep you warm on these chilly nights. 
 
Sizing is in inches for the chest
