Since you collect WW2 US rifles and pistols and want the German pistols as representative pieces I would want the best examples of the WW2 P.38 and WW2 era Luger I could find. I'd look for condition, not cheap.
As for the three Lugers offered, at those prices I'd take all three of them for their investment potential and as place holders while continuing to look for a high condition WW2 era representative piece.
