Mystery steel

[Sam Inglis]

Can anyone shed any light on this instrument that has appeared on eBay here in the UK?

It is branded Horn, but may well be a home-brew affair. Do the parts look familiar? It looks as though the seller has set it up wrongly, as it's clearly meant to be right handed.

The custom emblem and guitar emblem would be the front of the guitar. It has the wound bass strings on the back of the guitar, In the pictures. Which makes the guitar set up, For a left picking hand, Right foot activated pedals.
It is some ones dream, That became a reality. I have seen the "Custom" emblem. I believe it came from a vehicle.
The key head looks to be machined, from a single block of metal. The nut bar is mounted to the neck. Not part of the key head. The changer and its tuning screws look unusual. May be an early Push/Pull changer attempt.
It looks to be a Hand Made. "One Of A Kind".

The only parts that look familiar are the pedals, which are very similar to '60s/early '70s Sho-Bud, the rest looks home made as Bobby suggested. Based on the undercarriage pics, pedal and knee lever placement, it is definitely a lefty. It looks fairly symmetrical so it could likely be reversed to a right handed layout (perhaps it started out that way), but would probably be a lot of work for dubious gain. It's old and crusty, it might sound and play alright when done, it might not. The changer does appear to be a push-pull design, but it also has what looks to be an all-pull scissor mechanism in front of it that apparently activates the changer. Clem Schmitz built a Rube Goldberg contraption like that once on an Emmons PP. It might be a fun project if you could get it for $200-$250, but the £717.23 price tag (~$970 USD) is considerably more than I would pay.
