I think that we can safely rule out that it's a Peugeot frame for lots of reasons.
Here's a link to a Peugeot Pro-10 built at their Prestige Shop. Notice the difference in workmanship:
ipernity: 1982 Peugeot Pro-10 - by Peter Kohler
Educated guess: 1970's Motoconfort frame with a Gitane Tour de France fork! The giveaway is if there is a Flying "W" shaped shift lever stop brazed on top of the down tube.
Motoconfort was one of Motobecane's secondary marques that they sold in certain markets like the UK, Europe and Canada? alongside the parent brand. They produced similar models, for example the Grand Jubile had special made Nervex lugs while the equivalent Motoconfort Super Champion came with long point Prugnat "S" lugs.
1970's Motobecane Grand Jubile
1970's Motoconfort Super Champion (Note: some less experienced person tried to mount a Campy headset on this frame. The top lock nut is only holding by a few threads)
Motoconfort Super Champion - the Grand Jubile equivalent. Notice semi wrap over the seat stay cap treatment that was used on most of the mid range to top of the line Motobecanes up through about 1977. Also the Huret dropouts.
Like the Grand Jubile, both frames were only 3 main tubes Reynolds 531.
The chrome plating is a red herring just like the frankencomponents. It was probably done when the bike was repainted? Also the pre-plating polishing seems to have removed a lot of the sharp edged details.
Motobecane used chevron topped Vagner fork crowns on most of their mid to better quality bikes until the late 70's.
It looks like a 1972-76 Gitane fork with a Nervex DuBois fork crown or maybe a Tange replacement fork.
Why an ersatz Peugeot? Who knows.
In the mid 70's the Peugeot-Raleigh dealer about 3 blocks from our shop took a cheap gas pipe department store bike, rattle can sprayed the frame white and put PX-10 decals on it along with a "GUARANTEED NOT BUILT WITH REYNOLDS 531" sticker. They used it as a shop bike to make pizza runs!
Course, there's always the possibility that some Ocker up in OZ built the frame!
I have a 1974 Gitane Tour de France with a French made frame than came from "down under" ('stralia). It has metric tubes but the threads British !
