Hi John,
I know you've been busy as a one eyed cat watchin 2 rat holes....,but, if you have time to look for the cap for the air breather for a Oliver-Hart Parr 70 I'd sure appreciate it. Had about 6 returns on my ad and no one has the cap, just the entire breather system. If you need to sell the whole thing complete, I'll take it like that too, but I only need the cap and perforated screen. 
                                                     Thanx, Larry
