Let's not pick on Lighthouse Depot. They receive a certain number of autoship pieces as do many, but not all other dealers.

Those who ordered earliest from any dealer would be the ones to receive the pieces that arrive earliest at that dealer.

The balance of the two different fresnels are expected to ship to dealers in mid-May.

Probably by the end of May, depending on dealers shipping practices, those who have pieces on order from any dealer should receive theirs.

If you have not reserved one or both Fresnels, check around at dealers. You will probably find some unspoken for at dealers.
