Bit of a random one this.

Does anyone have a sources or information about what the Frateris Templars looked like?

Weapons/gear?

Armour?

Uniforms/colours?

My web-fu's drawing a blank...

To be honest I don't think there are any canon information about the how the Frateris Templars looked like. If you've got the Disciples of the Dark Gods book you can probably get some ideas about the general symbolical style of them from the Temple Tendency heresy but if you want to use them I think that it will be pretty much up to you to come up with their looks.

If I would myself however dare to make a guess I would say that they probably had a pretty dramatic look style to them, a bit like the modern Adepta Sororitas but without the fleur-symbols and probably with more standard Imperial symbology. I'm not sure of course that they used power armour but perhaps, due to being pretty numerous if I've understood things right, so they might not all be armoured with power armour like the Sisters of Battle.

In Disciples of the Dark gods, the listed Templar is with a good or best quality storm trooper armour, hell weapons or bolt psitol and with a chainsword.

I'm working from memory mind you, but they were rather solid opponents and combattant, that I recall; the Frateris Templars were, to me, the equivalent of Storm Troopers, with the Frateris Troops being your regular over-zealot guardsmen.

Well I had a look at my copy of the Disciples of the Dark Gods and I couldn't find any stats for Frateris Templars. The closest one I found was the Chantry Guard but that's probably pretty far off from how a normal Templar would be armed.

unfortunately nothing concrete,, but old school guardsmen with over the top ecclesiastic iconography,,, armies would be led by hordes of preachers, missionaries and confessors !! ? and of course goge vandire's name would be affixed to everything just above that of the emperor

Your question got me curious so i did some research of my own into the Frateris Templar and found out about them. Here is the link

wh40k.lexicanum.com/wiki/Frateris_Templar ...They were not what you are thinking exactly and in the DH/RT timeline they dont exist anymore..and havent since the Age of Apostacy. The Frateris Templar only existed for around 300 years..they were fully disbanded after the Vandire incident.

The Frateris Templar were ALL male...basically they were the Predecessors of the Adeptus Sororitas.

It would be interesting if the Ecclesiarchy had secretly reformed them to carry out their own hidden agendas though < insert diabolical schemes and maniacal laughter here> ( oh what a plotline that could make for galaxy spanning adventures..hehehe )

The Temple of the Saviour Emperor still exists in present-day Calixis, in the form of The Temple Tendency, and those might have Frateris Templar.

If they do, I would guess the FTs are embedded in the Imperial Guard in the sector. Pretty much the only place you can hide an army in Imperial space, is in another army. And the Imperial Guard is the only really mobile army around, so if the FTs are expected to carry out operations on any kind of scale, it's the army they can hide in.

Of course, there's the Frateris Militia as well, but while they're a pretty mobile bunch, they're not made up of trained soldiers, they're typically barely armed, and they generally get disbanded after a couple of decades at the most. So they're not a very good hiding place for a proper army. Also, they're always under heavy scrutiny from Inquisitors, Sororitas and kinds of Ministorum busybodies, who're all looking for something like the Frateris Templar.

If they're not supposed to be mobile, any old PDF will likely do. Though the more backwater the better, one would assume. Less eyes on them that way.

Wherever you hide them, though, they will presumably be armed exactly like the organisation you've hid them in. So.. If it's the Guard, they'll look like Guardsmen. If it's a PDF somewhere, they'll look like those do. And unless there's very, very few of them, they will more likely be recruited from the military organisation they're hidden in, than placed into that organisation. Because, again, hiding an army isn't all that easy in Imperial space. You can just throw up the infrastructure to train half a million troopers without someone noticing.
