Yes! This one has a wool lining.

In November 1939, the War Department Uniform Board was authorized to develop a jacket to replace the impractical service coat for field wear. The following September, the Army ordered a trial batch of 15,000 of the new jackets for troop trials. Most of these field jackets were made with substitute fabrics due to a shortage of the specified cotton poplin and wool flannel. Barely a month after production had begun on these uniforms, the Army approved the design, assigned it spec number 20 in January 1940 and issued contracts for mass production in February.

This a reproduction of the early "test" jackets, likely made during the winter of 1940-41. They can be distinguished from the "spec 20" models by the fabrics: The shell is the same cotton twill found on Winter Combat and jump uniforms while the lining is the wool serge from which flannel shirts were made. The spec label also lacks any spec number and is dated 1940.

Our pattern came directly from my original examples. In contrast to the later M41 Field Jacket, these lack epaulets, have slightly different cuff button positions, "V" shaped back gussets and the jacket is fitted with pocket flaps. Both jackets share the same overly long sleeves.

Fit: Order your normal chest size. These are relatively loose fitting, but not as baggy as an M1943 Field Jacket.

Like all WWII versions of the OD Field Jacket, these have longish sleeves which causes consternation for some modern enthusiasts- but they are historically correct.

Why longish sleeves? Some sources mention that initially the QMC was only planning to make one length to simplify sizing, and thus made them long enough to fit more or less everyone. However, this idea proved impractical, and they Army soon added long sizes to the tariff. It appears that they neglected to compensate for this change and left the overly long sleeve specification intact. Thus, they're historically correct.

Color: Olive drab no.3. This is somewhat less green than the olive drab no. 2 used for the lighter poplin cloth used on most M41 Field Jackets.

Fabrics: 100% cotton twill shell, 70/30 wool blend lining, Talon zipper.

Care: Dry clean only! These have wool lining which does not like washers and dryers.

Use/ wear: These were general issue for all soldiers in 1941, and worn until the end of WWII. So, they're correct for any US Army impression. Note that some NCO's and officers had epaulets added- as they can be found on a number of originals.

The names: These jackets are often called "M38" which is erroneous as the order to develop them wasn't even issued until the end of the following year. Contemporary Army correspondence and histories refer to all of these garments as either "O.D. Field Jacket" or "Parsons jacket". They don't differentiate between the early types with the flaps and the later ones we call "M41".
