Hey, just found this thread now while looking for one of my old ones. A couple things jump to mind.
Firstly, price is impossible to nail down exactly until the build quantity is established. There is a overhead cost of design as well as manufacturing that either must be paid by one bed or by ten. If ten are made each bed pays 1/10th but if one is made it must foot the bill by itself. One bed might cost $10,000.00 but 10 beds might be $50,000.00 or $5000 each (just numbers easy to divide, not a price point). Having said that, a price range or target could be posted.
Secondly, Yay!! Somebody wants to make beds!!
Thirdly, the pics posted by the OP may be just representations and not actual product (I believe this is the case). But they do look pretty good at a glance. I notice the bed to frame mounts are different than mine but I used my original 1978 bed to copy so maybe those mounts are what the earlier bed had? I dunno.
Fourthly, I made mine as exact as I could. Rib number, height, width etc all as close as I could measure my original bed at.
Finally, If I was making more beds they would be in the close to $5k range if there were like 10 of them. I made mine for too little and that may be why I don't make them any more given the labor I put in vs the reward in the end. I'm not bitter, it was fun but a lot of work.
Just some thoughts.
