Experience with big glass enema syringe?

We have seen these big, beautiful, all glass plunger enema syringes in movies.... they must hold around a liter or more of volume and have a rounded tip that is maybe 2 inches long and with a bore wide enough to push an egg yolk through without breaking it. Does anybody have any experience with these facinating products? And where or how a person might acquire one?

We've always wanted one...maybe two... so that we can administer interesting, creative, solutions that just don't work with standard equipment. Plus they are just so gorgeous and there's something about watching that full plunger push in its contents, knowing what's in there, in that volume, is going inside at the exact speed and pressure the one operating it desires....and the challenge of finding out how many plungerfulls one could handle.

I found large plastic syringes on Amazon, 300ml or 500ml for $10.99 1,000ml $21.59. They have glass but nothing bigger than 60ml. Look for laboratory supplies.

I did find a 1000ml glass syringe on Ebay but they want $299.00 for it!
