About 30 fixtures here from a old Ford plant.

I don't think they are T17s, but not sure.
The fixtures have no bulbs.
Seeing the bolt location for the ballast, it looks like it has the long ballasts that attach to the inside of the cover.
The bulb holders appear to be white.
I can't identify the manufacturer from the pictures as the picture are not very clear.
I am sure a LG member can though.

However local pick up only.

I would like to have one or two, but not 30 of them.

Since the seller is apparently a antique dealer, they may consider selling them one at a time.
There would of course be more money made by selling them one at a time.

I hope they are relisted with a shipping option.

A old classic preheat.

I always liked this style of fixture as where I used to work a long time ago there was a bunch of these in use for many years even though most of them were converted to rapid start in the later years when the preheat ballast finally gave out.
http://chicago.craigslist.org/chc/tls/4540381868.htmlI sure would like to buy this lamp, but it is local pick up only and the seller will not ship.
I tried to make shipping arrangements, but the seller would not cooperate.
John (Diesel Nut) tried to meet the seller driving to a half way point, but the seller would not do that either.
It has been listed for three months and still not sold because the seller will not ship or have it picked up and shipped by a shipping company.
I am not going to drive 1800 miles to Woodstock GA. to pick it up.
Oh well what can you do?

I don't think I have seen one of these fixtures before.

However there is no mention of what to do when they start spewing tar.

They leave you to figure that part out yourself.

I bought a holder with a fuse and two thermal 186 deg.F cutout links mounted to the ballast just in case.

I am not worried so much about a fire as I am the smoke and the resulting tar smell that is near impossible to get rid of.
