I have 3 designs of circuits. If there is no capacitor over the transformer, the voltage will go to the sky and a 1000v npn may be used ex. bu810 it's a hopeless design! it can run but the bu810 gets hot as in the hell With a capacitor (~ 33nf) a 50 volt transistor can be used. base voltage fluctuates very negative, resulting in an anti paralel diode (1n4148) over Vbe (arrow to the base) With FET (IRFZ44 from banggod), it runs without cooling. Vbat 3V can draw 9mm. spark . the zener can be replaced with a 1n4148 if Vbat<5v see Diagrams and Drain Gate curves

Ordered these extra units along with the "Arc Ignition Module" which uses similar kind of Transformer, so that if something goes wrong I have extra units to replace the one which came with the module. As for the shipping part I ordered it on 31.01.19 and received it on 20.02.19 (20 days), the parcel was packed carelessly but no contents appear to be physically broken (I will update after I use each of the units and state if they fulfilled the requirement).

Alles ist gut, danke, schnelle Lieferung!

Everything is fine, thank you, fast delivery!

Zwei der drei Einheiten kamen mit gebrochenen Kernen an. Konnte sie wieder zusammenkleben, aber die Ausgangsspannung aller drei ist geringer als erwartet.

Two of the three units arrived with broken cores. Was able to glue them back together, but the output voltage of all three is less than expected.
