Great closeup,w. bits of M.gl I'd not known before,& the distinctive spines are just what I've been banging on about in the Jonathanwallace case. Iwas wondering if you'd fancy commenting on the jonathanwallace case (either there or the forum topic he opened). The spines make it beyond debate i.m.o. & a forum with 1 reply has much better chance.
