Rod,
Sorry I'm late to the party.
The first one is
Bochmann MS269 (click to enlarge).

It's a machine cancel, and the text is
WHW Ein Volk hilft sich selbst, which roughly translates as
Winterhilfswerk, A nation helps itself. The
Winterhilfswerk (Winter Relief Program) was ostensibly an annual charity program, though there are significant doubts as to where the money actually went. Yours is from Weimar and is the
B variety in Bochmann, meaning the circular cancel is to the left.
The second one is
Bochmann MS313 (click to enlarge).

It's a machine cancel, and the text is
Helft der Jugend Heime bauen!, which roughly translates as
Help the youth build homes! It's also the
B variety. There were only two locations that used this cancel, Reichenberg and Wien (Vienna).
