Model Railroading > BLMA N Scale 48" Fans

I'm getting down to the last of these items and could use more.
BLMA  N Scale #82 or #83  8 blade 48" fans 5/pk
BLMA  N Scale #84 or #85 10 blade 48" fans 4/pk
would be first choice, I'm only using blade itself, none of the grills or supports

Since I model in HO, I'm not up to speed if there are others (besides BLMA) who
offer or offered  this item?? I'm using these to represent a 24" +/-  fan in an HO
application. Anybody know of a hobby shop who may have stocked these things??
Thanks for your help.
