Help With Some Stamps

Hi everybody. I have found these stamps but I can't find the place they were issued. And I don't know either if they are postal stamps. So if anyone could help I would appreciate it.

I'm new here myself so take this with a pile of salt, but the German would imply they're Bavarian Railroad stamps. That should narrow it down a bit hopefully.

That's possible, Relm. Thank you.

The second one is indeed a railway stamp from Bavaria

The cancellation on the first one seems to be from Switzerland (Uetliberg ?) but the picture is too blurry (can you read something other than K 3 ?)

the inscription on the second stamp says "Bavarian State Railways", so in the Erler/Juenke catalog this stamp is from the post-WW I 1920 set. It is the lowest value, 20 pf stamp (#41). it is not rare. Three varieties are listed; they are: light green, yellow green, and printed on reddish paper (slight premium).

If this stamp had a "Kgl. Bayer. Staatseisenb." (Royal Bavarian State Railways) imprint, then would have been from either the 1904, 1906, or 1911 series, depending on watermark.

Thank you vayolene and bookbndrbob.
