I recently found a deal on these but cannot find anything about these irons. Does anyone know what model and year they are? I know they are Fujimoto but can't find anything else. 

They look like one of the open models muscle backs made of SS400 steel.

if it is the regular muscle back,  then the specs are 

Club	Loft(°)	Lie(°)	F.P.(㎜)	Weight(g)
4	24	60.5	4.5	250
5	27	61.0	4.5	256
6	30	61.5	5.0	263
7	34	62.0	5.0	270
8	38	62.5	5.0	277
9	42	63.0	5.0	285
PW	46	63.5	5.5	293

They also have a muscle back that has an internal cavity. (hollow)  But judging from the narrower sole width , I think this is the solid one piece version. 

Hope this helps. 

 

 

ive.played the  hollow version .. quite a different feel. wasnt sure if i liked it  or not.. felt almost like nothing..very soft.. maybe too soft

prgr tune is a similar feel.
