A member on here was attempting to repro the assembly but that was 5 yrs ago and he hasn’t been active since 2016.

I spoke with Ivo at the War and Peace show in 2017 and BAIV was supposedly repro’ing them. However, I was never able to get their customer service to reply to follow up email inquiries. Seeing a trend here?
Out of desperation I ended up buying the last set that Hebding had last July...wish I had bitten the bullet several years ago since the price practically doubled.

?
I don’t know nor have heard of any other sources. Good luck...I think it’s going to come down to someone having the parts cast and/or machined for a completely reproduced assembly. There’s definitely a market for them!
