As per our telecon on 22 Jun, I have attached a photo of subject firearms and a closeup of the mag housing on the SAS-3 (semi-auto sten modified).
The photo of the 3 firearms are, from top to bottom:
1)deleted-not relevant
2) deleted-not relevant
3) SAS-3 (modified to mkII) serial ###X. This is the kit found at
www.semiautosten.com and uses some components from an origional sten. It is approved in the USA by the BATF as a newly built semi-auto, not capable of automatic fire. It is shown here normal 32 round sten magazine (once again, pinned to 5 rounds) inserted, and a 5 round magazine next to it. It fires from a closed bolt, and the feed horns of the bolt are far enough back that it will not feed a fresh round if the hammer/firing pin is forward, inlike a normal sten where it features an open bolt with a fixed firing pin. The receiver is only capable of allowing semi-auto fire as well, and the tube will not accomadate a regular sten bolt as it is of a smaller inside diameter. The magazine housing was an unserialised housing to which I have added my own unique serial number.
I will be dis-assembling the sten into it's major components later today (the mag housing and the receiver) and cutting the welds on the receiver to seperate the trigger group from the tube. I, personally, was always under the belief that the receiver was the firearm, and the trigger housing never was an available replacement part to a sten. When the CFC decides what constitutes the firearm, I will replace whatever component qualifies this as a "converted auto" with a newly built and if need be re-designed component. I am still of the belief that this particular firearm was never capable of fully automatic fire, cannot easily be made to do so, and should not be classed as a prohibited firearm. To say the trigger group is the firearm is questionable, as a F/A or C/A sten is fully able to fire a round, and in fact will completely empty the magazine, if the trigger housing is removed. The magazine housing is also fairly insignificant to the firing of a sten (it can still be slam fired), and while that part does usually contain the serial number, so does the wooden stock on a cooey model 82, and it is not overly critical to the operation of that firearm.
Anyway, when your side of the house decides whether or not this firearm is prohibited, and what part of a sten is prohibited, please let me know so I can perform changes if required. Also, please do not hesitate to contact me if you require any further information.
Thanks.
