Honestly, the most important barometer for how you did is how do "you" think you did.
Please dont take that the wrong way. I'm truly not trying to be mean, just stating an important aspect of collecting.
You can check "ended" auctions to see how other similar bows have sold to know if you were in the ballpark of others.
It's in your weight range, you liked it enough to bid on it and from your initial statement you "scored on what you think is a decent deal".
That's really all that is important. I'm happy for you. Sounds like you did great. Let us know how it shoots. It's a handsome bow. Not sure how rare it is but someone may chime in.
Good Find, Thanks for sharing it with us.
