Newbie - bear with me....help with frame manufacturer

Hi,
I didn't know what I was getting into when I rescued an old steel frame bike from the scrapyard (based in Berkshire, United Kingdom). I've got an ID on most of the parts, but, I really could use a hand on identifying the frame please.

Front wheel [27"x1.25"] - Maillard (France, March 1986) (marked "Maillard 13 86" on hub)
Rear wheel - Marked "W Germany 079" - no clear brand....
Front derailleur - Marked "Shimano FE Product of Singapore"
Rear derailleur - Marked "Shimano 600 RD-6207 VIA Japan" [circa 1984-1986??]
Cranks - Marked "170 Japan SR" "34" on Left crank and "25" on Right crank. Also "81"
Freewheel sprocket - Hub is a Suntour "Perfect" Maeda Industries Japan 5speed "BK" (circa 1985 November??)
Stem - Aluminium ITM 70 (100mm), c.25mm diameter and 170mm top to toe - quill stem with round/cone expander.
Handlebars - British made stamped "GB 021 79" Aluminium.
Brake/suicide levers Stamped "PAT APP 642251" and "LH" and "RH" (clearly left and right)
Brakes - "Chang Star Deluxe Y730"
BB - 68mm shell, bracket stamped "Tange Industries"
Serial number - SO236, or, S0236??
Fork tube (inner is stamped "Akisa 80") and front forks no stamped identifiers.
Seat post - "Stop.....and Made in Taiwan" (!) ; the seat might be leather or suede.
Frame? Help please....My best guesses at the moment; I think it might have been a Viking, or an Asian/Malaysian manufactured frame/forks - around mid-late 1960's. The lack of brazes suggests it might be in this date range, interestingly there's a threaded braze welded onto the front right fork, made for a headlight. The previous owner/s then pimped it up in the early-mid 80's with Shimano stuff.

Hope you can help
Thanks
Neil

Re:

The bike looks a bit like a Falcon Champion Du Monde or another similar bike in the Falcon range.

Falcon was the bike that sprang to mind for me too,

kinda Coventry eagleish...........

Thanks very much for those reading my post and looking at the photos. Having searched....a lot, I agree that it's likely to be a Falcon from the late 60's/early 70's. It think red was it's original colour, before being repainted in blue. This past post helped to firm up my conclusion:
