WTB/WTT Modamag Collosus + Extention for $$ or light(s)

[Genna]

To finish a long planed project I'm in search of a Modamag Collosus with 4 inch head + extention tube and battery holder for a 36 Volt built. I can pay for the host or I have enough lights and stuff for a trade.
Please let me know over pm.

Thank you!
