Hi!
I'm looking for someone who is willing to sell me a NOS (or very little used) 175W clear BT shaped MV, and ship it to me to The Netherlands (in quality packaging ). Shipping costs will probably be astronomical but so be it.
Thanks! 

Have you also considered getting clear mercury vapor lamps in other wattages?

I have seen that if you don’t mind finding clear mercury vapor lamps in other wattages, Japan is another place to look as clear mercury vapor lamps were also quite common over there, but have become less so and more overpriced in recent years. Buyee has been a good place to search for them and they can easily help ship lamps to you from Japan to the Netherlands without much trouble in many cases.

I can send you links for my findings of Japanese clear mercury vapor lamps in a PM to you.
