Question anyone familiar with these speakers?

Hello all, hopefully this is the right place to post this.
I came across a listing for these german-made speakers - WHD BR 140-1/8 - for 200 euro.
They seem to be in really good condition and the seller is reputable.
Info online for them is very sparse, but they do have a hifi wiki listing, and some additional specs from the seller, roughly translated:

System Configuration

• 3-way bass reflex system with front-firing port
• Reference WHD chassis components
• 25mm silk dome high-frequency tweeter
• 43mm silk dome mid-frequency tweeter
• 175mm grooved special paper woofer cone
• Removable metal protection grilles

Technical Specifications

• Nominal Power: 70W
• Musical Power: 140W
• Impedance: 8Ω
• Frequency Range: 35Hz - 25,000Hz
• Crossover Frequencies: 900Hz / 3,500Hz
• Color: Black
• Dimensions (H × W × D): 520 × 300 × 240 mm
• Weight: 9kg per speaker (18kg pair)

Has anyone came across the brand and/or model?
Assuming I'm able to test them out, would this be a good deal?

How much were they new, and how old are they? Warranty?

"Made in West Germany" frames the age question!

I'm pretty sure these are mid-late 80s! So info is pretty sparse even though the brand seems to have a bit of rep.
