#89) Locating Replacement Parts For Old Librascope Products

Occasionally, Librascope Memories receives requests from both Libravet and non-Libravet readers for assistance in locating parts they need for old Librascope products. Some past examples include requests for locating L107MA disk memory castings required for replicating the "Mr. Fusion" mounted on the rear of the DeLorean Time Machine in the movie "Back to the Future" (see Blog Posts #2, 12, and 14). Other examples are various parts needed for WWII vintage Librascope Balance Computers and MK 7 Barrage Computers. A few of these requests have also been posted on this Blog.

Needless to say, old Librascope product parts are very hard to locate, and we can't always help you find them on a timely basis. So, here are some suggestions for where you might find the part(s) you need:

1) Museums that specialize in military, computer, and aerospace equipment. Frequently, they will have equipment or parts in the back room that they are no longer interested in displaying and would consider selling them, or donating them to a worthy cause.

2) e-Bay. Simply search on e-Bay for "Librascope". You might also consider posting your requirement there as a potential buyer.

3) War Surplus Stores (See Blog Post #64 for a local example).

4) Craig's List

5) Apex Electronics in Sun Valley, CA

When Librascope was still in business, the Company would often sell its surplus parts to Apex.

If all else fails, please contact me and we'll try and help you. Of course we would appreciate hearing about any successes you've had too. Either send me an e-mail (see above), or leave a Comment on this Post.

Finally, we suggest that you subscribe to this Blog (see instructions above), so that you can be kept up to date on any related matters.

Thanks,

#10) W.W.II "Librascope Balance Computer for Boeing B-17" on e-Bay - HURRY if you are interested.

This unusual piece of equipment was donated to the Oregon Air & Space Museum, and has been deemed surplus and thus is being offered for sale. The current bid is only $10.49, but bids close this Monday (November 15, 2010) at 14:09:14 PST. The owner's description, from the e-Bay web-site, follows:

Mounted in a simulated black leather covered case, the device measures 16” x 11” x 3”.  Manufactured by “Librascope Incorporated, Burbank, California, U.S.A. (Does Lockheed come to mind?... for it was one of the companies Boeing authorized to build B-17s.)... and bears patent number 2179822.  It is completely mechanical (no electricity required), the “balancing” exercises being applied by turning the dials.  These in turn move systems of interconnected lever-arms and cables, ultimately arriving at two principal measurements... (1) “Total Weight” in pounds, and (2) “Center of Gravity Position” as a percent of Mean Wing Chord.  There are dials to insert such info as gallons of oil, fuel in gallons, bombs in pounds, etc.  Other dials can be turned to record the weights of personnel, gear, equipment, etc.... in the nose, control area (cockpit & adj. area), entrance, rear gunner area and tail section.  Finally there are large screws at the LL and LR corners... these being for “weight adjustment” and “balance adjustment.  I have tilted the “computor” (sic) panel forward so I could view the works, and they all seem to be fully inter-connected and in working order.  Testing the dials, each causes one of the two main indicators to swing... seemingly effortlessly... that in itself, if you saw the works hidden behind the panel, is amazing.  On top of that, this is the first either I or the curator of the museum have ever run into!
