1./ Versuchsverband des O.K.L. - May 1st 1945

[Feldpost]

Hello again to everbody, especially to the ME 262 enthusiast!

Some time ago I aquired a Luftwaffen "Soldbuch". The last entry was a discharge note from May 1st, 1945. It was signed by the commander of Uetersen airfield together with a small rubber stamp:

Versuchsverband des O.K.L. / 1. Staffel

I have two questions about it:

1) Are there any other sources about the location of this unit in April / May 1945? Where and when was this unit disbanded ? Somebody told me it was maybe in Kaltenkirchen, which is very close to Uetersen?

2) My point of interest is the Fliegerhorst Uetersen (near Hamburg). An eyewitness, who was a little boy in 1945 and used to live at Fliegerhorst Uetersen, since his father was an officer there, told me for several times he saw two or three Me 262 in the last weeks (month ?) of the war standing in Uetersen. I have no idea, to which unit they could belong. Maybe it was the "1./Versuchsverband OKL" then? Did they have any Me 262 in service in April 1945 ???

Any suggestions welcome

Best regards
