New Ware NWAM0285 1/48 Grumman F-14A/B/D Exhaust Nozzle Mask Set for the Hasegawa kits 

(Brand new but arrived with 4 parts missing from the sheet and it's for a kit I don't have!  There are still enough plus spares on the sheet to mask a complete model but I can't sell it as is for full price and it would cost me more for the postage to send it back hence reduced price.)
