i bought an unopened package of 5 heads at an antique store. they are in a blister pack and say grayling michigan on them. i can't post pics yet because my camera charger went missing. my questions are what year (roughly) would these most likely be from.are they standard thread if i chose to use them? also, they were $16 . was that a fair price. what grain would they be? thanks for any help

If they are Converta then they have to be 1964. 8-32 thread...Bear set the standard for the industry. They will weight 115 gr without the bleeder  and 125 with the bleeder plus the screw-in adapter at 20gr. Nice find!
