Question : I picked up a 1961 Pre Label 4157 Orphan Shell that I’m rebuilding . Do the original 4 point butt end strainers have failure problems like the original Micro Sensitive Throw off’s ? I’m going with the new throw off but I have a chance to pick up a new old stock 4 point strainer or should I not waste the money and install a 5381 single point butt assembly . Plugging holes and drilling a new hole is not a problem . Thoughts on both would be appreciated .
