I'm trying to order a Gobo's (B-size?) for either Strand Century model 2321 or 2211 it appears that there is a slot but no one is able to help me identify for certain what size and demensions the Gobo holder is and where I can get one?
If memory serves me right, those are the old grey radial beasts, right? The old 6x9s we had at college didn't have a pattern slot, not that I recall. If it does have a pattern slot (got any pictures?), a regular B-sized holder should fit, I think.
the gobo holder is the same as the Strand Lekolite - indeed a number of the parts are interchangeable including lens tubes, yokes, shutters and the complete shutter assembly. I have gobo holders at home which I made from aluminium sheet. I can post the dimensions if someone does not post the name of a supplier. I use B size gobos in these fixtures
As a matter of fact, yes, as the graphic below from City Theatrical shows (#2130 vs. #2140). There'll be a little play from side to side, as the SH is narrower by 3/16".
I never had much success with this fixture using gobos. I had five in battleship grey and 1 in black. I replaced the stepped lenses in the grey units with non stepped lenses which improved them as a fixture but they still did not do much with gobos. I scrapped them earlier this year and I use the lens barrels as alternates for my Lekolites which will project a gobo.
