thank you!
on a side note, the grill cloth is black. I know sunn had some later models with the black cloth, but I didnt think any of the early 70's models had any. By looking at the thread and the back of the grill, it's very obvious that it's not just spray painted or re clothed. interesting. I know there was no specific pairing during this time period, but maybe this was to be paired with a model t as it appears it would match perfectly.
