Falcon frame. Can anyone id this frame?

[BikeMad37]

I'm wondering if anyone here can help in identifying this Falcon frame?
I purchased it a couple of years ago for £80 just because I liked the look of it but I can't seem to id it.
All my searches point to late 70's but I cannot find this exact frame in any forum pictures or catalogue.
It looks like it takes a 26.4 seat post.
Although the frame looks well made and good quality it's doesn't seem particularly light.
The interesting thing (for me!) is the strengthening plate on the inside of the front forks.
I also noticed that a few weeks after I bought this, the seller was advertising another one of these, same colour, same size???
Does anyone here know what this frame is?
Thanks in advance

Have you looked at the catalogues here?

Like you say, looks late 70s/early 80s. The style of decals should narrow it down a bit.

Does the frame number have an M prefix? If so this indicates Japanese made Miki. Very nicely made but as you've noticed not light.

The serial no. is not very clear but the first digit is definitely a G followed by what looks like 09022. There is also a random number 4 in a different area.

Hi, yes I have looked through them several times but can't seem to track it down.
Quite a few that come close but always something to rule it out!
Maybe it's not actually a Falcon, just badge engineering by someone!

Falcon frame numbers are a minefield. Some bikes in the same batch came with different parts. I think @jim haseltine may be able to shed some light on this.
