This appears to be very similar in design to the Microflash which was used as the basis for Darth Vader's lightsabre. I do not know the ins and outs of which parts the Microflash and the Heiland shared but the similarities are there for anyone to see. There are, however, differences, too.
I know the Mircroflash unit is worth around £1,000 in it's unaltered form. This Heiland unit, though, appears to be around $100 looking at eBay listings:https://www.ebay.com/itm/HEILAND-SYNCHR ... 2210862929
And fuckety fuck that annoys me. I had bid on this lot which appeared at Astons at the end of November last year. It hammered at £650 which after costs came in around £900. The camera and associated bits and pieces in the lot is worth about £300-£400:
It was described as:
"MPP Micropress 5x4 Press Camera Outfit with Rare Microflash. Comprising MPP body, focal plane shutter slow (condition 6F) with Schenider Xenar 135mm f4.7 lens in Syncro-Compur shutter, speed slow from 1/60th; MPP 120 roll film back; uncommon MPP 'Star Wars light sabre" style Microflash unit; film pack holder; Polaroid back; 9 DDS (various conditions); wire finder; instruction book; Gossen LunaSix meter etc. All in fitted outfit case".
Having checked eBay at the time I decided the flash unit was worth around £1,000 (as mentioned). Having just checked eBay again, I see the same flash unit (looking at one or two identifying marks) sold two weeks after the auction for £1,500:https://www.ebay.com/itm/Rare-MPP-Micro ... 7675.l2557
I shouldn't have been so sensible. The annoying thing was it was just me vs. the winning bidder from £150 up to £650.
And having checked his other sold listings it absolutely is the same flash unit as here is the camera from the lot. Not bad. Looks like the seller made £800 or so on the lot:https://www.ebay.com/itm/MPP-Micro-Pres ... SwI8laNkeS
