Unidentified Marks:

Looks like a normal 'Berlin Design' mark, but they were founded 1970 by Kaiser from Staffelstein, so that does not fit.

'THREE CROWN CHINA' mark applied by Unger & Schilde for U.S. distributor Jon H. Roth - but who knows more?

'P.M.' on crowned shield above 'C.W.'

Note from Heiko Haine: 'perhaps Triptis mark for export?' - I doubt it.

'BERLIN' above crossed staves, superposed 'C' and 'HANDGEMALT'.

Same basic mark as before but without the 'HANDGEMALT' addition.

Simple red 'GESETZLICH GESCHÜTZT'.
(Picture by Antoinette M. Cesena).

Just 'GESETZLICH GESCHÜTZT' and the initials 'A.E.'.

A simple crown over 'BERLIN'. Crown looks like that of Adolf Schedel fom Neuses (Bavaria). Could 'BERLIN' be the series?

Looks like (but is not) a mark used by the Porzellanmanufaktur Plaue.

From redecorated Zehendner item; can't be Greiner or Roesler as the periods don't match and this mark is missing a capital 'S' on chest.

Crowned 'A' and 'H' above 'W'.

Crowned 'A' and 'H' above 'P'.

A-R-T or A-T-R (???).

'QUALITÄTSPORZELLAN' surrounding a capital 'B'.

Mark containing the term 'GESCHÜTZT'.

Crowned initials 'G-K' flanked by lions.

Weird set of initials reading 'JSK' or 'SJK'.
(Picture by René Ruitenberg).

No information on 'ROTHENWALD PORZELLAN' so far.

'ROTHELM' over 'PORZELLANFABRIK' and 'C D P'.

'A H' and 'BLAU DRESMER', no idea so far.

'W' next to a square symbol above a capital 'S'.

Eagle with scepter and orb, also single stylized 'k' or interlocking 'lr' (bottom left), often claimed to be Leube from Reichmannsdorf.

Crown above capital 'M' and 'SAXEN'.

Sticker with the words 'KERAMIK KERUSKA'.

Crowned shield with 'L' often claimed to be Ernst Bohne Söhne.

'FRAIN' is a town in Moravia, but who there (or elsewhere) actually used a mark like this ?

Crowned circle with a lion, text unreadable. Here shown in grey but also seen in red.

Superposed initials 'J H' or 'H J'. Often incorrectly claimed to be a Huettensteinach mark.
(Picture: Margherita Fusco)

No other marks but this eagle with 'PREUSS. PORZ.' (for 'Preussisches Porzellan').

Mark simply reads 'AVM HANSA'.

Reads 'SIEGERT & ANGELBECK'. No manufacturer known with that name, so it could be a distibutor/retailer.

Initials 'W B' above 'SCHLITZ'.

Crowned initials 'C G S' with the central 'G' being larger than the other two letters.

Crowned laurel wreath around a capital 'G', all above initials 'P M'.

Sticker showing the initials 'A K' and a lion.

Sticker showing 'KUNST' above a jug above 'KERAMIK'.

Capital 'S' in a stage setting. Seen claimed as Schaller mark by Winterling.
