Propliners are war birds too

Propliners! Love 'em!
Brief list of some US types with military versions:
Lockheed Electra = basis for P-3

Without intending to be contentious: did any L188s serve with any military force, and if so in what capacity?

From Wikipedia:

Military operators
Argentina
Argentine Naval Aviation
Bolivia
Bolivian Air Force - 1 from 1973, still in use in 1987.[52]
Ecuador
TAME
Honduras
Honduran Air Force - one 188A from 1979
Mexico
Mexican Air Force - one 188A from 1978 to 1987.
Panama
Panamanian Air Force - One 188C from 1973 to 1984.

The Honduran ship was recently purchased, brought back to life, and flown to Canada (I believe).

There is one true B377 known to still exist in Israel. There was a project a few years ago to try and get that aircraft and bring it back to the US to put back into the air, but it seems their funding never developed fully.

There is a picture of a Boeing 377 Stratocruiser at the Israeli Air Force Museum on the Wikipedia page for that type. Picture is dated 2007, which I would guess is the plane mentioned above. Amazing if there are no other survivors for the airliner version of the C-97.

I don't believe the aircraft you refer to is a Boeing 377 Stratocruiser. My understanding is that those had round fuselage windows, whereas the aircraft in the Israeli Air Force Museum has KC-97-style windows. The aircraft in the museum is said to be either the former KC-97G 52-2736, sold to Israel as 4X-FPN/039 (=assuming the aircraft is the original '039'), or the former KC-97G 53-365, sold to Israel as 4X-FPM/040 but painted for museum purposes as 039. Even the Wikipedia article itself says it's the latter, in the last line in the 'Operational history' section.
