Crudites advice needed

I am slowly but surely getting my On-One 456 built. I'm building it for my son who, unlike me, can actually ride a bike
He's coming over to the UK in June to spend a few months here in the summer, he's 21 and he'll be taking the bike back with him

The build is coming along fine, I [obviously] have the frame complete with headset
Forks: RS Revelation Team, U-Turn 150mm
Wheels: DT Swiss X430 on WTB LaserDisc Superduty hubs, s
Brakes: Avid Elixir 203mmF/186mmR, Cleansweep 3 rotors
Stem, bars, seatpost, saddle and grips
I am still to buy the derailleurs and shifters, no rush those are minor details

I've just bought me an FSA Xtreme Chainset Mega Exo in 32/22 crankset and this is where I need advice. This is an external type BB which is what I want

But I also I want to fit a chainguide/bashring combo on the bike and I've been looking at the Blackspire Dewlie as an option
So, I see they come in three flavours, one just stays 4 bolt, white, the second option is ISCG and then ISCG 05
Please advise me as to whether it's a "normal", ISCG or ISCG 05 for the 456 frames?

HELP! :!:

Think he'll like the bike?

    Normal. ISCG has 3 bolt holes around the BB for mounting a chain guide to, ISCG 05 has the holes slightly wider spaced. You can see an ISCG 05 mount on the Ti 456. Assuming you have a steel 456, there's no extra tabs, so you need a normal chain guide.

    Herein lays the confusion, the 456 summer seasondoes have the 3 tabs! And this is the summer season frame

    So, should I assume it's an ISCG 05?

    Ah, I see your problem. From the picture, that appears to be ISCG (you can see that it's fairly clearly smaller than the ISCG05 on the Ti 456), but I wouldn't like to bet on it. The best idea is probably to give On-One a ring in the morning.

    EDIT: Just realised you already have the frame. Here's some drawings of the specs:

    ISCG05

    A few seconds with a ruler will tell you.

    Your failing as a son. I'm married and have my own place on the other side of Europe from my parents, but if they offered to buy me a bike, I would happily oblige them.

    This is not quite "scrounging" more of a surprise gift for him coming to visit me...

    I got an email from On-One confirming the 456 Summer Season is an ISCG fitting

    Thanks for the feedback guys

    Oh also the mounts on the summer season are quite often on the piss. But nothing a little persuasion with a medium grade hammer won't resolve.
