Jolana Diamant LP 6-string electric guitar, made in Czechoslovakia

Link: cheesyguitars

There were a couple of different modifications of Diamant. We'll mention just a few of them.
Brand: Jolana, made in Horovice, Czechoslovakia
Pickups: two HB. There were at least two types of them: soapbars with closed pole pieces (shown) and opened - with no covers. Sometimes there's a "Spectrum" logo on them.
Controls: two volume, two tone, 3-way switch. A rare modification used a chickenhead switch instead of the regular Gibson-style one. Knobs were usually transparent, sort of LP custom design.
Hardware: chrome
Neck: bolt-on (yes!), 22 frets, trapezoid inlay.
Binding: body (both face and back), neck. The binding is made with a sort of creme - white plastic, although its color is still not creamy enough to match Gibson.
Bridge: tune-o-matic/stop bar. Tune-o-matic is somehow modified and features a 3D adjustment option for each string. Stop-bar is bigger than a standard LP.
Tuners: Jolana standard. It is used on almost all the Jolana guitars - oval heads and oval back covers.
Materials: maple neck, unidentified body woods
Finishes: black, red, sunburst (rare).
A couple of "modifications" : pickguard is screwed to the body, and the lower strap button can be screwed out and it reveals a screwdriver. wow.
