Ovdje se vide dva različita pristupa potkalibarnom zrnu.

Žiroskopi C, A, B

Gdje si ovo iskopao.

Na lijevom žiroskopu, žiroskopu bočnog valjanja tenka, sa lijeve strane vide se dva klatna. Za uzdužni i bočni nagib tenka.

Koliko mi se čini, vide se tragovi skidanja ograničavača hoda jarma žiroskopa. Krivljenje ograničavača hoda jarma žiroskopa je veoma čest kvar na žirobloku, i to ako je neispravna kočnica topa kod opaljenja, odnosno, ako nema dovoljno ulja u kočnici.

I to sam mijenjao na svoju ruku gdje sam stavljao čiviju iz tvrđeg materijala.

Suvenir potkalibarna
[ Attachment: You are not allowed to view attachments ]
Jednog dana nabi se cijev u zemlju, vozač vrhunski. Marševski položaj bez stabilizacije ne bi nam Vladin sistem pomogao. Izvukao sam zemlju koliko sam mogao rukom al ostadoše trunke nedohvatljive. Riješenje da ispalimo barutno punjenje i izduvamo smeće. Nije bilo vremena hopa, hopa, hop mi čistimo top. Mislim da je dobro rešenje, ali nije zgoreg i vaše mišljenje. I tako ostade suvenir, jasno vam je zašto nije kumulativna ili trenutno fugasna. Poslije je bilo igrarije sa štapićima i kartončićima. Kafa na šporetu nikako da prokuva. Ubacim komad kartončića, kad u milisekundi voda iskače iz džezve a iz šporeta gdje god sastav izbija plamen. Prilično su šuplji šporeti.
Bilo je u zadnje vrijeme zanimljive rasprave, uglavnom sam posmatrač, ali gledaću da upadnem malo u priču. Nisam bio u nekim trenutcima, ali možda se vratim na neke tematike. Dodam mišljenje i upitam pitanje.
Usput, je li iko zna od koje je puške bajonet?

Pozdrav!

Neka od verzija H&K G3?

[dzumba]

Према облику ножнице (јасније би се видело да је нож окренут "пљоштимице") пре бих рекао да је у питању нож за неки старији карабин или можда аутомат М-57 само што је рукохват мало измењен.

[Bozo13]

H&K G3, Iranski?

[coaveliki]

Bila neka rupa u zemlji.Nađemo vjetnamku maskirnu (alfa), rakiju (šljiva) i bajonet (nepoznatog porijekla). Evo rakijeeee i odjednom svima osmjeh na licu.
Moguće da je iranski, nož je crn (šminkeraj), nema oštrice, nije za krmokolja.
Pozdrav!
