Hi,
The FL47199 could be a part of the MG-17 weapons system. In the parts catalog FL 47200 is the EPAD 17 for the cowling mounted MG 17's and the FL 47506/7 are the MG's themselfs. The FL 47000 numbers are mainly weapons related.
FL 32601 is the Pressstofsteckdose P25 (connector to the REVI connector) mounted under the cowling and behind the MG's
Hope it helps,
Cheers,
Sander
