Any idea what this 'elapsed time' clock used on?

Friend of mine gave me this as a 'Spitfire clock' :highly_amused: (aren't they all). However it has me intrigued and I don't think it's military but probably off something 60's era Civil? [ATTACH=CONFIG]231535[/ATTACH][ATTACH=CONFIG]231536[/ATTACH] Anyone have any ideas? Made by Camerer Cuss. Runs perfectly but not really my thing - not sure what it'd be used for as it only measures up to 12 minutes.

Looks like a normal clock to me with the hours in the centre and minutes on the outer scale, not an 'elapsed time' clock. Do not know what it was fitted to, but clocks of different makes are often interchangeable. Regards.

Well, it's got a 1955 date if that helps.

'Looks' like it, I agree. Except when you start it, the outside is seconds, and the inner is minutes and runs (and operates) just like a stopwatch. And it states on the corroded label on the back 'Elapsed Time Clock' :confused:

Ah, but the image you included is inverted - that sort of thing confuses people.;o)

A.P.112G-0805-1 A.P.112G-0805-1 gives the following description for, CLOCK, ELAPSED-TIME, TYPE N.L. 1395 Introduction 1. The clock, Type N.L. 1395 (Ref. No. 6A/5184), is an elapsed-time aircraft instrument and provides an accurate time datum when flying on a Q.D.R., thus enabling the various stages of a let-down to be accurately timed, or for a given rate of turn to be maintained for a predetermined time. 2. This elapsed-time clock is complementary to the time-of-flight clock, Type N.L.6520-VC (Ref. No. 6A/5183). The two clocks constitute a set. I have this set as being fitted to the VC10. I have always wondered what the VC in the part number stood for, perhaps I have just figured it out?

Excellent - many thanks for the info and having had a poke around, I have found it fitted to a VC10.... [ATTACH=CONFIG]231547[/ATTACH] The Elapsed Time clock is fitted to the P1 panel just to the right of the RH yoke arm, next to the ADF instrument which would make sense.
