You  mentioned multiple beamsprings, will you be selling others? I would be very interested in buying one.
i thought i found a sneaky way of looking up old stock by searching the keyboards by their part numbers. evidently i'm far from the firs one to try this, as it turns out all the sites i found that said they had stock were either scams or didnt actually have any at all.

at the moment all i have is my 5251 parts unit that i'm currently rebuilding. i'd love a full size 3278 keyboard with usable palmrest, as the steep angle and abrupt bottom cutoff is not my cup of tea.

Check out these two links-

Low profile 5251 case hack- https://deskthority.net/viewtopic.php?f=7&t=17339&start=

Alternative shell concept for 5251- https://deskthority.net/viewtopic.php?f=7&t=14292&start=

I recently discussed the alternative 5251 shell with Lot_lizzard and cited the fact there is increasing demand due to the sheer number of 5251 boards coming out of the woodwork. One thing that caught his attention was the beamspring to MX mount recently developed by the community. If we can get enough interest to hit MMQ then he may be willing to put together a modern TKL beamspring kit that utilizes your existing switch modules. This would be along time from now(after his model F tkl) but IMO a TKL beamspring with a modern low(er) profile shell would be really amazing to type on if it ever happens.

In the mean time you could just put bumpons on the inner assembly and use it without the case. It won't have the vintage aesthetic or booming sound from the solenoid but it will feel much more comfortable to type on. My personal idea for a modern 5251 case is basically just a wood frame surrounding the inner assembly. It would be too thick if it was mounted in anything so the inner assembly would have to be the actual bottom part of the case design.

Hi I have actually managed some of this. I have a working 60% Ansi Beamspring keyboard conversion prototype.

It is more DIY currently. I am finishing up a case for it so its not just wires everywhere.  Not sure if I am going use a metal front or a wooden wrest.

I have been slowly updating with new part production methods as well. It is not really at a GB stage and I am not really interested in running one, but all the pieces are there if someone wanted to run one.

ideally the best layout for me would be the normal 3278 keys plus a function row above or even two rows like how the 4978 is. itd be a mighty battleship.

Now the base plates are so shiny!

Just need to address the key stabilizers and outer casing and it's ready for the rebuild!
