Leather Biker Jacket Men's XL Black Shearling Liner Custom.
There are no visible tags or brandings or marks on the jacket. 
I do not know if he made this himself, or had it custom made to fit him.
His surviving sister was certain he made some of his riding leathers but did not know which ones besides a kilt.
I went with XL as the size, I normally wear XL in my jackets that I want a looser fit with, and L when I want a tight fit.
I am approx 5' 10" and a bit over 200 lbs. When I put this on, its roomy and loose on the top end
shoulders and chest. His sister said he was a big man and that he was taller, bigger chested, and
had broader shoulders than me, the arms were also longer than what I am used to with them almost 
engulfing my hands at the cuff ends, and at my waist it was snug, currently my waist would be size 36-38. 
I would think this is best suited to someone 6 feet tall or over with a bigger chest and wider shoulders. With it
zipped up and laid out as flat as possible, the shearling really puffs it up, I measured around it and got 51" at the chest.
This jacket is heavy, on my scale in a box it showed a weight of 12.5 lbs. Putting the jacket at at least 11.5 lbs in weight by itself.
The shearling lining the front and back of the inside is thick, long haired, and dense.  The sleeves are lined with a fabric material.
Brass ykk zippers and snaps complete the jacket with leather pull tabs on the zippers. No holes or rips in the leather or the liners,
it smells of leather as I often see with higher quality leather clothing. Shows some wear marks on the sleeve ends from previous use
and some few scuff marks in spots nothing highly noticeable.
