Jacket:

No pockets on chest because a vest was intended to be worn over the jacket.

Tag and Collar:

Stamp:

Barely legible date stamp indicates it was made for the East German Army (NVA; Nationale Volksarmee) in the first quarter of 1988 (1/Y) (source: https://www.onvauc.org/east-german-uniform-date-chart). “1958” is not the year.

Collar has elastic like an MA-1 flight jacket. “K 48” is the size, with the “k” meaning “kurz” ( German word for short). This size is equivalent to a US Medium Short (source: https://www.varusteleka.com/en/page/east-german-size-chart/22445).

Pockets:

Internal pockets are only on the arms. The rank slip is for a Gefreiter (equivalent to a Private First Class, source: http://www.nva-flieger.de/index.php/mil/dv/10-0-005/dienstgrad.html).

Rank Slip Loop:

Rank slip goes on a buttoned fabric loop.

Cuffs:

Also has elastic for insulation like the P59 Denison Smock.

Elbows:

Padded elbows.

Inside:

Inside of jacket as an integrated holster like the TTSkO paratrooper jacket. The fabric loops for foliage on the back are sewn onto fabric reinforcement on the inside.

Opening:

The buttons have been positioned so that the gas flap needs to be buttoned in to fully close the jacket.

Bottom:

Elastic cinch, again for insulation?

Load Bearing Vest:

Vest body is made from same twill fabric as East German uniforms.

Button:

Same pebbled plastic button used on other East German uniforms.

Chest Pockets:

Left Bottom Front Gas Mask Bag:

On the front in the bottom left side. Meant to hold an SchM-41 gas mask.

Magazine Pouch:

Same design as standard separate belt-mounted East German AK magazine pouch. Like all pouches on the vest, this is stitched onto the main body.

Upper Back Pack:

Backpack is a patch pocket on upper back. Loops above the flap are meant to attach a chemical protective cape (Schutzbekleidungsumhanges, SBU). These do not have any metal hooks attached, a characteristic of the last East German Fallschirmjager vests.

Loops are a synthetic webbing material.

Sticker inside pack:

Back Gas Mask Filter/Canteen Pouch:

Holds 2 gas mask filters and a canteen. Made from synthetic material.

Bottom Back Small Pouches:

General purpose for a thin rain jacket, bandages, and other small items.

Hooks:

Body of vest is secured by snap hooks.

Inside:

Holster on inside of left side (as worn). A fragment of a Makarov holster was found inside:

Tag:

Size tag.
