To be honest CSM, that isn't like any blank firing adaptor that I have ever seen! Ours incorporate the whole foresight block and are threaded much further back so I'm not sure that our 'standard/EMER' Thread will be what you're looking for.
What say you KG?

Crimped blank eh....... I am of the opinion that the hole in the front of those two BFA's is TOOOOOO large to allow operatioin with crimped blank. While I don't know about, nor have I seen the internal configuration of the yellow and red BFA's but based on my limited experience as an Armourer, but the blue wood nosed blanks would simply destroy the muzzle opening of those BFA's after a very short time.
The wood nosed bulletted blank would tear the usual standard UK BFA (drawing shown) to shreds quite quickly and even shoot out the angled bullet smasher/deflector. As a result, we used to keep these 'masher' barrels in the Armourers shop where we could keep a vary eye on them. At Battlesbury, the barrels were kept nose-down in a tub of oil after use so that they could be closely examined after every exercise. Lose the deflector/smasher and the wood bullets would travel some distance before disintegrating. I don't know HOW far they'd go before breaking up. Maybe Tone E the ammo man can tell us!
I won't give you the UK type barrel thread CSM because it might lead you up the garden path and wrongly but can I suggest that you ask a local engineering shop to use a TPI gauge on the threads and you'll soon have your thread spec.
Interesting................

I'll check one of my Canadian BFA barrels as I have most of the TPI gauges and PM you with the spec's.
We used mainly the crimped blanks and not the wooden bullet ones in Canada. We had two lengths of crimped blanks.

How did you fare with the magazine spacer insert with two lengths of crimped blank Warren?
have you seen one of these BFA's?
Incidentally KG, the BFA in the drawing was upgraded in the 60's so that you could remove the guts in order to clean it as they'd quickly fill up with shi..............., er..........., debris. Identifiable by the extra 1/4 BSF bolt towards the front

Back to you Peter.......
Now to finish my tea and back to fixing the fence..
By the way, the long blanks did not work worth a **** with the regular mags however there was a minor alteration to the receiver with the short blanks and the mag with the insert as shown.
Kev: drop me an email on the home addie if you would........

So was the red parallel BFA a Canadian one for short crimped blank Warren (and presumably the yellow BFA too)? If KG's drawings are anything to go by, it's a blessing that I didn't give out the standard UK thread

Interesting Warren that you have the same pattern BFA too.
Just to make things a bit clearer the picture of the yellow BFA csmarcher posted is mine that was red but I painted it yellow to comply with normal BFA yellow colour !.......will have to repaint it back to red I think :-)
I have noticed a few of these crimped blank BFA's have the gun serial number stamped into the face of them,does yours Warren ? (will be in touch)
