VoPo stuff I haven't seen before

[Wilhelm]

I'm no expert on VoPo weapons but I like them and I have a few. I just picked up another Luger and it has some stuff I haven't seen before. The slide shows some rough machining one the sides and there are no markings on top of the chamber. The barrel has the usual Crown/N but no date too. I have never seen these characteristics before. The rest of the pistol is typical VoPo. I took pictures but I don't know how to post them on this forum because I'm a technoidiot! I'll be posting this over at gunboards too and will provide a link. I'd like to know what you guys think. Thanks for any help in advance.
