I have a puzzle, that I'm hoping someone might be able to clear up for me.

In Britishicon service there were 3 main types of BFA used with the L1A1 rifle.

First was the L1A1 model, very possible these were imported from Canadaicon, as they are the exact same model as their 2nd model C1A1 BFA.

Second was similar in appearance but has a wingnut and a better retaining catch, it was called the L1A2 BFA.
There was a modified version of the L1A2 BFA in which the wingnut was replaced with a spring and nut arrangement. I call this the L1A2(m)
Third model is the L6A1 BFA, its a massive, solid BFA capable of trapping a bullet if needed.


My question relates to a reference in the 1965 training manual, two pages (p123/p124) are dedicated to the description, use, safety etc in relation to the ' THE BLANK FIRING ATTACHMENT (L4A1) '. Unfortunately there is no photo of the detailed BFA and although it sounds similar to the L6A1 I don't think it is, as the description of the L6A1 is different.

L4A1 BFA Description from Pam 3B, 1965, page 123
The blank firing attachment (L4A1) consists of an inner tube, choke pin, knurled sleeve, main spring and housing. The housing and main sleeve are painted bright yellow.

Fitting: Ensure the rear part of the knurled sleeve is covering and flush with the teeth on the housing. Fit the attachment to the rifle as you would fit a bayonet, press the knurled sleeve clear of the housing teeth, turn clockwise until tight, release the knurled sleeve, ensuring the teeth engage. it may be necessary to unscrew the knurled sleeve slightly in order that the teeth can engage.


L6A1 BFA Description from Pam 7, 1975, page 5-1
The blank firing attachment consists of an inner tube, knurled sleeve, a main spring and a housing. The attachment is painted bright yellow.

Fitting: Unscrew the knurled sleeve until the threads on the inner tube are completely disengaged from the housing. Insert the inner tube into the flash hider and position the rectangular hole in the housing over the the bayonet lug (see fig 107). Screw up the inner tube, using the knurled sleeve, until the attachment is tightly locked onto the rifle (the serrated teeth on the housing will begin to engage before locking is complete). When the knurled sleeve is fully tightened, unscrew it two clicks, to assist removal of the attachment after firing. Test the attachment is secure.

As you can see these are totally different BFA's. Dose anyone have a pic of a L4A1 BFA or better still a real one?
