This is a budget-bow riser and looks very similar to one that PSE used to market several years ago; they called it a BullsEye, as I recall. Those bows were made in Korea, but I do not know by whom. Since the PSE bows like this came with a maximum draw weight of 35#, I would not over that weight.
I would start looking at a Hoyt dealer for limbs. I have another possible source, but will not be able to speak with him until next week.
