Latzsch Alto Trombone Model and Date

[Jamesamp2000]

Hi all, this is my first post here.

I wanted to see if anyone can help me suss out the model and approximate era of this instrument. I'll put a link to the original listing with pictures below.

It's a Latzsch Alto Trombone in Eb, springs in the slide, dual bore slide. It doesn't look like anything on Latzsch's website now, but then it also doesn't have the silver bell rim, ornate end of slide and tuning slide, or the friction grip instead of a screw to put the slide and bell together like the vintage German altos by them.

It's an incredible instrument, the slide is perfect and makes an amazing sound, I'd just like to know more about it. If anyone has any clue, please do let me know!
