A couple of days ago Jan Kalivoda commented on finding GMT by lunar
altitudes. As far as I can see this method (and comparable methods) was
discussed in "Navigation" and the "Journal of the Institute of
Navigation"quite some time ago:

Chichester,F., Longitude without time, in: Journal of the Institute of
Navigation, Vol. 19 (1966), 106 -107 (with comments by D.H. Sadler, one
time superintendent of HM Nautical Almanac Office, p. 107 - 109).

Evans, J.J., Longitude without time, in: Journal of the Institute of
Navigation, Vol. 19 (1966), 392 - 394.

Sadler, D.H., Longitude without time, in: Journal of the Institute of
Navigation, Vol. 21 (1968), 234 - 235.

Ortlepp, Bruno, Longitude without time, in: Navigation (Washington),
Vol. 16 (1969), 29 - 31.

Wright, Frances W. , Examples of  Moon Sights to Obtain Time and
Longitude, in: Navigation (Washington), Vol. 18, 292 - 297.

Kerst, D.W., Longitude Without Time, in: Navigation (Washington), Vol.
22 (1975), 283 - 292.

Luce, J.W., Longitude Without Time, in: Navigation (Washington), Vol. 24
(1977), 112 - 115.

Kerst, D.W., Comments on "Longitude Without Time", in: Navigation
(Washington), Vol. 25 (1978), 87 - 90.

Sadler, D.H., Lunar Methods For "Longitude Without Time", in: Journal of
the Institute of Navigation, Vol.31 (1978), 244 - 249 (with a historical
note pointing out that the Board of Longitude in 1802 resolved  that it
"will not in future take into their consideration  any methods of
ascertaining the Longitude founded on the Moon`s Altitude...).

A short section on lunar altitudes can also be found in:
H.M. Nautical Almanac Office, A Modern View of Lunar Distances, in:
Journal of the Institute of Navigation, Vol. 19 (1966), 131 - 153 (p.133
- 134)
