Believe this is the customized Triple Threat Sports as well.
Good luck! That is a very rare sweater.
There is no chain stitching on the crest. I believe this was before the small block “pinhead” version of the 80’s.
Think I have seen 2-3 in the past few years. Bob or some of the more experienced Hawks guys might be able to shed more light on this.
The wool are HEAVY and itchy. Not ideal for warmer games but can be nice when using a long sleeve undershirt.
Also, the 3/4 sleeve style are very long in the arms.
Sizing of the newer M&N is a more slim cut. USA and other versions.
Sizing is a bit different than Majestic but the quality of the USA made jerseys is amazing.
I would go down at least one size. Normally wear 46-48 and XL M&N is bigger in the pit to pit measurements.
What version are you looking at?
