Penn 113H vs 113HSP

[CFish]

Hi guys, I have recently acquired a few 4/0 Special Senators with the hopes of using them for some wire line trolling.  I understand the "special" aspect being the faster retrieve but I'm a bit confused as to the difference between the 113H and 113HSP.  Of the ones I have the only difference I'm seeing is the graphite frame on the HSP.  I have 3 older (maroon side plates) 113h's and they all have the chrome spools.  I was under the impression that the HSP had the chrome spools built for wire line.  Arent these chrome spools on my 113h's just the same as the HSP or am I missing something??

Thanks I'm advance...

 The SP means special purpose

The special purpose means "wire line", and will have one piece bonze spool and frame posts instead of graphite half frame and aluminum spool. Although some HSP reels may have a graphite frame, .most do not. Before graphite frame and aluminum spools, all 113h were made as wire line reels, and standard line as well
