Old Stamp Dealer Covers From Latvia

Under normal circumstances I would think twice before buying a dealer-to-dealer cover, but not with this one since it's a registered cover with mixed franking. The interim era covers from Latvia that I've seen with mixed frankings are the ones that I've purchased, only a handful, so not many around.

This registered large-sized cover was sent by stamp dealer Leo Zirinsky from Liepaja, Latvia, to stamp dealer A. Weisz in Vienna, Austria, on December 20, 1923. The original name of the stamp dealer - Beckmann - is hidden by the black bar overprint in the upper left corner of the cover.

Postage is affixed to the backside of the cover, which was quite normal for the period in time. 1x 40sant., 1x 12 sant. and 10x 1 sant. gives 62 santimes. The orange 9 rubel stamp has a value of 18 santimes; in total 80 santimes. The rate for registration was 20 sant., the rate for a letter abroad of the 1st weight class (<=20g) was 20 sant., so this registered letter must be franked to fit either 2nd or 3rd weight class, which it also looks like (I haven't got information on the proper rates).

Another dealer cover is shown below and was sent by the very prolific stamp dealer Georg H. Jaeger (sometimes George H. Jaeger) from Liepaja, Latvia (Libau is the German name of the town). His covers are often listed for sale at various venues, this one got my attention since it's a mixed franking cover.

The registered cover was sent June 27, 1923 from Liepaja, Latvia to a person in Sköfde, Sweden. Postage stamps are affixed to both sides of the cover with 1x 9 rubel, 1x 6 rubel and 5x 2 santimes definitives. The rubel stamps combined give 15 rubel, with a value of 30 santimes.
Registration is 20 santimes and an ordinary letter abroad of the 1st weight class (<=20g) is 20 santimes. Correctly franked, that is.

Lovely covers!

@John Freibergs, many thanks, you're welcome.

Yet again a dealer cover, but this time it catched my fancy for a different reason.

This ordinary cover was sent by Ed. Sneiders (without diacritics, in German that would be Schneider), the shortened name could be Edgar or Eduard (in Latvian: Edgars or Edvards), or perhaps something else. The sender's address also indicates that stamps and coins are their speciality (speciali markas un monetas), and the address is Brivibas iela 34 (Freedom Street), which is in the very centre of Riga. This street was actually renamed to Adolf Hitler Strasse during the relatively short German occupation.

The letter was sent to Prague, in the Protectorate of Bohemia and Moravia, during the German occupation of Latvia in WWII, when it was part of Reichskommissariat Ostland. The postmark says Riga, Deutsche Dienstpost Ostland (DDO) and the date May 20, 1944.

The cover is franked with Hitler definitives of the German Reich overprinted with Ostland. Two se-tenants of machine coils (6 and 4 pfennig) and a 6 pfennig postage stamp, in all 26 pfennig, which makes the cover overpaid by 2 pfennig, since a letter of the 2nd weight class was 24 pfennig. There is no postmark of arrival on the backside.

The "Aa." round rubber stamp was applied as a transit mark since the letter was not censored.
