Help Identify vintage windscreen

[Silverwood]

First time poster here...just purchased a 65 dream and it came with what looks like a vintage windscreen frame without the plastic...searched every where I could think of but could not find any info. Reaching out here for any info someone might have.

Really have no idea what it is. I suspect it is not a stock Dram screen because it looks like the mirrors can't be used with it.

Looks like they adjust out for mirror clearance ...I think its some after market brand, someone suggested Buco but i cant find much info on it. I'm a complete nube on the ca77 & this is my first foray into vintage Honda and just trying to get educated...I'm used to restoring vetts where there is a abundance of info on everything.. so appreciate any incite..
