WW2 1930's Nazi German army feldgrau trousers size 28

For sale here we have a very rare pair of what we think are WW Feld grau ' walking out' trousers, or dress trousers for a German officer. After a little research it seems that at the start of the war it was quite common to have these made privately with an allowance which would explain the hand sewn button holes and lack of markings inside. In addition the size of 28.5" waist is in keeping with a soldier during this period. The fabric is typical Feldgrau wool. Attached are images of replica pairs we found scouring the web, the ones we have for sale seem like an amalgamation and simplified version of the different types available. If you were having a pair made remember, you wouldn't need side adjusters or brace buttons and belt loops, one would suffice. Hard to judge the value of these since we couldn't find a single pair online past or present so offers welcome.
