Input on Legacy Vivitar 19 MM f 3.8

I have been looking for a Legacy Ultrawide prime at a decent price and finally found one

appears to be in new condition always cased , this one has the big 62 mm filter ring

anyone have one of these in their collection ?

Would like to know what to expect  oh and it is a FD Mount.

I was only able to locate one other one on Flea bay for 140$ and it was a beater .

Thanks
