Atlas/Sunnen VGS 20 collet chuck collets

[ProPower engines]

Anyone know where I could locate collets for a Atlas collet chuck that was designed for the Tobin Arp 19000 qand 20000
seat and guide machine or a Sunnen VGS 20 machine.
This was made or supplied by Atlas before Kline bought them out
I did try K line buy they were no help.
The sunnen collet chuck uses ER 20-30 style collets but the Atlas chuck has a larger center allowing larger reamers to be used
Any leads would be a big help
Thanks again
Dave

I have a Goodson sold, T Meyer branded one that takes DA180 collets.

Not sure its the same as atlas but its definitely not the Sunnen with the er collets.

Largest collet is 3/4"

Will get you pictures if it helps.
