Lego vintage 934: Roof Bricks 33 degree (1973)

Lego Vintage 934 Supplemental Roof Bricks set (NOT a racing Porsche!), first released 1973. Slope and peak roof bricks, also known as Set 934: Lego Red 33° Roof Slope Tiles Set. Seen elsewhere for €39 as NOS, so I'm pricing this well for its near NOS status. OTHER LEGO SETS: I have ~17 complete and excellent condition boxes of sets from my 1970s childhood available, priced cheaper than identical items on eBay (some pictured): * 4 * 225 * 263 * 271 * 293 * 294 * 295 * 361 * 433 * 659 * 692 * 933 * 934 * 935 * 937.
