[CjBobrow]

Do these designations refer to any-known aircraft?

Rumpler R.C.1 1915?

or

Albatros LDD 1915?

I do not know where you found a mention of these designations, but there is no Rumpler R.C.1 in the book of Kranzhoff - Edmund Rumpler - Wegbereiter der industriellen Flugzeugfertigung ISBN 3-7637-6127-6

The abbrevation LDD is often used for Land Doppel Decker, this could be a reference to the many early biplane Albatros reconnaissance planes (B-series).

These designations were used in Hugo Junkers January 4, 1923 presentation to the Royal Aeronautical Society in London which was made on his behalf by Her Ingenieur Mierginsky (Junkers was too ill to travel) and W.J. Stern of the Air Ministry Laboratory in South Kensington.

There are any number of reasons why these may not be correct designations. Tork1945 thank you for the LDD definition.
