There usually seems to be an example or two of Matty available, but price is outrageous.
A fellow board member "sniffy5" seems to have been collecting the set for a while and is down to these final 10 (which he has posted as WTB on the b/s/t) and he hasn't seen them recently in ANY condition:
86 SHOTTEN 93 PRATT 103 JACKSON 118 KONETCHY
90 SMITH 95 KEATING 104 SAIER
91 PECKINPAUGH 96 BECKER 115 BRENNAN
You'll notice many he needs are higher numbers. I've been sorta collecting the set over a couple years, picking one up every now and then (have like 30 or so) and it seems like the higher numbers in general are tougher to come by, with the first 20 or so pretty easy in comparison, except for #1 Knabe which is also tough.
Its a fun set, but can get expensive quickly so thats why I'm going so slowly with it.
Good luck!
