[Seaplanes]

Based on information in BA/MA files RL 10/365 and the log book of Uffz. Fries, the Lehrstaffel (See) Travemünde (unit code 6L+) was formed in June 1938. On 01.11.38 the unit was redesignated 10.(See)/L.G.2 (unit code L2+). On 15.09.39 redesignated 3./K.G.30.
In June and July 1938 the unit received the following new aircraft:
He 60E W.Nr. 2478 6L+B0S
He 60E W.Nr. 2479 6L+C0S
Do 18D-1 W.Nr. 715 6L+E0S
Do 18D-1 W.Nr. 716 6L+D0S
He 59D W.Nr. 1835 6L+G0S
He 59D W.Nr. 1836 6L+H0S
Bf 109B-1 W.Nr. 354 6L+NOS
Bf 109B-1 W.Nr. 355 6L+O0S
Bf 109B-1 W.Nr. 356 6L+P0S
He 114A W.Nr. 2282 6L+W0S
On 09.06.38 the Staffel received three He 114A W.Nr. 2268, 2269 and
2270 that arrived from Heinkel with the transfer codes HE+JI, HE+KI and HE+LI respectively. They were given the unit codes 6L+T0S, U0S and V0S, not necessarirly in the same order. It is remarked that the 0 = Null (zero). However, it seems that 6L+T0S was given to He 114A W.Nr. 2373.
The Staffel also operated some aircraft that were flown with their
"civil" registrations:
W.34hi (Land) W.Nr. 1492 D-ONYY
W.34hi (See) W.Nr. 1491 D-OVUU
Ju 87A-1 W.Nr. 0870186 D-IBEX
On 19.09.38 the unit received the He 59E W.Nr. 2597 marked BA+HO from Walter Bachmann, Ribnitz (hence BA+ for Bachmann). It is stated that the transfer code was only for the flight from Ribnitz to Travemünde and had to be washed off after arrival.
Hope this is of some interest.
