HelloI have for sale 10 solid brass polished portholes. I bought these new 7 years ago and have now replaced them with identical chrome ones.They are ready to fit using M5 or M6 countersunk screws.There are 4 large 17" Diameter and 6 smaller 14" diameter.The large take 14 & 1/2" glass, and the smaller ones 11 & 1/2" glass. (Not included). For all dimensions see pictures. (Fits Standard glass from Midland Chandlers)These retail at £89 for the large and £54 for the small. So £680 all in. See Black Country Metalworks for price check.They are no different now as to when I got them, so at half price a bargain.Item may appear less polished when received as brass will slowly tarnish over time.I would prefer collection but can post at a cost of about £29 (which is an educated guess)Good Luck
