There was no shutter on that straight tube OmegaOriginally Posted by jnanian
I picked up as surplus in 1958 or 9. I think it was
war surplus; olive drab IIRC. Don't happen to
recall what model it might have been?
I didn't think to mention cold vs warm start tubes. I'd
guess 5/8 inch the size the OP needed. Three thousand
Kelvin. That's lower than expected. Dan
