Thanks Mark,

I have a pair of RPM’s 6A-778 (early type) for the Comet project and was sold a pair of RPM generators said to be the correct ones No 6A-4333780 (KGA043). This number seems long but is on the label on the side.

I have been offered another RPM which looks closer in design to those originaly used ..No 6A-1429 and I wondered if the generators I have will still work, but have also seen some other generators 6A-1549 .This is why I was asking about a list to try and help me see if things will match up

Will the lists you have help?

Thanks

Ken,

my listing is a RAAF WW2 Stores publication “Types and Location of Instruments in RAAF”, and as such only lists instruments etc used in the RAAF’s aircraft, however the 6A/778 is listed

The entry is:

RAAF Ident No: G6A/778
RAF Ident No: 6A/778
Maker: A.M.
Type: mk IVB
Detail: 0-5000 (A.C.) Lum.
Aircraft fitted: Beaufighter, Mosquito DH98, Sunderland mkII, Mosquito Mk XVI

The same document lists the following generators as suitable for the same indicator and aircraft, (using the same entry labels as above):

G6A/780
6A/780
A.M.
mkIV
AC for mk IVA & IVB 4:1 ratio

G6A/889
6A/889
Kollsman
mk IV
AC for mk IVA ind 4:1 ratio

Hope that might be of some assistance

Regards
