Weihrauch HW 35 from 1970 with F mark break barrel air rifle caliber 4.5 mm HW35

Very nice HW 35 air rifle. See pictures.
System and end piece have matching numbers.
Spring and barrel seal are new. Works perfectly!
Still the good quality from the Weitschuss air rifle era!
Very popular with collectors and connoisseurs.
On the underside of the stock, there is a cross-shaped spot where someone put something in, I can't explain it, it's clearly visible in the photo.
