Vtin,
If the seller can't provide you with the information, I suggest you contact JRDG and ask them directly. They should be able to tell you about the design features of that particular Model 8, and the modification stage it has undergone, if any. I would check with the seller before you do that however, as the serial numbers are 6-character alpha-numeric, not 7 as you have listed.
JRDG can be contacted at "jrdg@jeffrowland.com", or you can speak to them directly at 719-473-1181. They have an extremely helpful technical support group, and all my emails to them have been responded to in 1 to 2 days.
