Asking around in the past I was told the castings for the elbows are difficult to make and cost prohibitive etc... Which is why they aren't reproduced. What I dont get is that someone is reproducing those death trap girder forks for 16H's which have some pretty complexe castings. I wish these people would re-direct their efforts to making item's such as these elbows which would sell like hotcakes if they were of any quality and a decent price. If they can reproduce a complete fork for the price they are asking, I would think the elbows could be made for a decent price. I am of course writing this in the hopes that they might monitor this site and decide to do it! 
Sam they would need one or a good drawing to copy. The guys who have the originals are guarding them

That doesn't really like the original war time elbow at all and needs a lot of changing to make it only look a little like it.
Here a picture of mine.

Correct Henk.
I do see now that there is quite a difference.
Will keep an eye opened for it..
Cheers,

Yes, I know, you'd need an original from which to make a mold, and I undertand the turn off it is sending something like that to the India or Pakistan etc... Probably wont come back. Henk I think you should take one for the team and risk it! I'm kidding of course

I am sure it can be viable in the Western world. I tried to have some parts made in India, and all that happened is that prices charged are higher than the initial batch that we had made in the Netherlands!
They are not half daft out there!
But it can be done, just need the loan of an original.

Ron, and forum,
I have several, and have been trying for the last 20 years to have them copied! as some people know, I have lent Peter Long of Cornucopia my original filter and elbow connection, and he had the filters made, better then any other copies on the market, he asked several of his supliers to have the elbows made, and nobody could do it for an affordable price!
It seems, that due to the nature of the castings, and how they have to function, ie. slide into each other, you need steel casting moulds, just like carbs are made, and that is the snag, it's just too costly to have these made.
But with new technology at hand, new drawings are made up, using a 3D scanner, where plastic patterns can be made, and these can be used for sandcasting.
Hope to have some samples next year, and those who know me, I only go for quality, and hate cheap copies that don't fit or look like something out of a sci-fi movie.
Cheers,
Lex
