All right this is the only mild one that I have been able to find...
4 lb. deer
1 lb. bacon
5 Tbsp salt
1/2 tsp black pepper
2 1/2 Tbsp brown sugar
1 1/4 tsp crushed peppercorns
I haven't gotten around to trying it yet so I can't really say how close it is to what they make in Belleville. If you do decide to try it, I'd cook a small test patty before you stuff it to see what you think in case you need to make any adjustments. I would also add cure #1 to it.
I have one other place I can check later & if I come across any others I will let you know...
