hi there,
we recently excavated the remains of an aircraft and we are absolutely certain it is a Douglas C-47 43-48328.
The identification is confirmed by:

• Confirmed identity of one of the crew members, a holder of the Order of the Red Banner, whose loss matches the location and date.
• Cross-referenced Soviet and German military reports describing the crash and recovery attempts..

However, among the remains we recovered a compass data plate that does not match the standard instruments normally fitted to Dakotas. Or,maybe there are series with remote Indicating Magnetic Compass Indicator AN-5730?
Therefore, we would like to ask the community:

1. Did the Soviets replace cockpit instruments (including navigation compasses) on Lend-Lease C-47s during service or overhaul?
2. Are there any records or technical orders indicating which equipment the Soviets commonly substituted when servicing Lend-Lease aircraft?

Additionally, we would be grateful for help identifying several of the recently excavated components. We can provide detailed photographs and measurements if needed.

Any documentation, examples, or comparative photos would be greatly appreciated.

Welcome to the site.

Ad the image no.4 ... the data plate seems to be the FT-255-A shock mount of the Western Electric Modulator Unit BC-456-B / GE Dynamotor for instance. Or just a similar unit. In other words something like the FT229-A but just of different dimensions.

and the FT-225-A with the BC-456-B modulator and GE Dynamotor units

The image 3 is a piece of the data plate of the three-receiver rack .... for Western Electric Radio Receiver Set R-24/ARC-5 R-25 or BC-453, BC-454, BC-455-B, SCR-274-N Command Set for example.

The image 6 (A,B,C) I assumed that's the same data plate. it is of the Indicating Magnetic Compass Remote Transmitter AN5730-2A by the General Motors as I may read it correctly.

No 27 in the scan.

and one more question. There were few spark plugs AC LS87 on site. Were they used in the R-1830 engine?

A couple od net surces state the AC 171 18mm aviation spark plug. The other ones mantioned in the maintenance manual ... RC-34S, RC-35S, 7KLS2, RB19R. Other manuals for different R-1830 models show the differnt spark plugs. See below. But it looks like the AC LS87 could be used for the engines rated under 1200 horsepower in various aircraft. The specific planes include those equipped with the Pratt & Whitney R-1830 Twin Wasp or Wright R-1820 engines. Among them is the Douglas DC-3/C-47 Skytrain.

R-1830 S1C3-G ( R-1830-92) powered major of DC-3/C-47s.


R-1830-75 and 98
