Ok, I have been researching Mitchell Enginering a little in a quest to turn up a sweep arm. Now, I was interested to discover they were a small enginering shop that prior to making turntable parts for Transcriptor made model parts for the film industry. I therefore believe that it is possible only parts, possibly reject items were supplied as props rather than the props department buying numbers of sweep arms to strip for parts. If this is the case the metsl parts used for the anti security blade could have been from anything that was in the reject bin, or laying around in the shop.
However, if we assume the variant sweep brush holder is the correct part, does any one have any dimentions that I can replicate some in aluminium?
Thanks. Bobby.
